course: C Srbject Code: Q. Greedy puppy Tuzik is a little dog. But despite the fact he is still a puppy he already knows about the pretty things that coins are. He knows that for every coin he can get very tasty bone from his master. He believes that some day he will find a treasure and have loads of bones. And finally he found something interesting. A wooden chest containing N coins! But as you should remember, Tuzik is just a little dog, and so he cant open it by himself. Actually, the only thing he can really do is barking. He can use his barking to attract nearby people and seek their help. He can set the loudness of his barking very precisely, and therefore you can assume that he can choose to call any number of people, from a minimum of 1, to a maximum of K. When people come and open the chest they divide all the coins between them in such a way that everyone will get the same amount of coins and this amount is maximal possible. If some coins are not used they will leave it on the ground and Tuzik will take them after they go away. Since Tuzik is clearly not a fool, he understands that his profit depends on the number of people he will call. While Tuzik works on his barking, you have to find the maximum possible number of coins he can get. Input The first line of the input contains an integer T denoting the number of test cases. Each of next T lines contains 2 space-separated integers: N and K, for this test case. Output For each test case output one integer - the maximum possible number of coins Tuzik can get.

course: C Spbject Code: Q. Chef and Balls Chef has bought ten balls of five colours. There are two balls of each colour. Balls of same colour have same weight. Let us enumerate colours by numbers from 1 to 5. Chef knows that all balls, except two (of same colour), weigh exactly one kilogram. He also knows that each of these two balls is exactly 1 kg heavier than other balls.You need to find the colour which balls are heavier than others. To do that, you can use mechanical scales with two weighing pans. As your scales are very accurate, you can know the exact difference of weights of objects from first and second pans. Formally, the scales will give you the difference (signed difference) of weights of the objects put into the first pan and the second pan. See the following examples for details If you put two balls of the same colour on your scales, each ball to one pan, the scales will tell you that difference is "0". But if you put into the first pan some balls of total weight 3 kg, and into the second pan of 5 kg, then scales will tell you because the second pan is 2 kg heavier than first Similarly, if you put 5 kg weight in first pan and 3 kg in the second pan, then scale will tell you "2" as first pan is 2 kg heavier than second. Input & Output The interaction process have two phases. At first phase you perform sequence of weighings on the mechanical scales. At the second phase you should output the colour of the heavier balls To use the mechanical scales, you should print "1"(without quotes) and then print two lines, the first line will describe the enumeration of colours of balls on the first pan and second line should that of second pan To describe some pan, you need to print one integer n - the number of balls you put in this pan, followed by n space-separated integers colours of the balls you put in this pan Once you have printed required data, you can read from the standard input one integer - the difference of weights of the first and the second pans To output the colour of the heavier balls, you should print "2"(without quotes) and one integer in next line - colour of the heavier balls. Constraints Each colour you print should be between 1 and 5. Source Code #lnclude int main() f int x; printf("1\n"); fflush(stdout); prlntf("3 1 2 2\n"); fflush(stdout);

course: C Srbject Code: Q. Game of Strings Harsh and Akshara are playing the Game of Strings. This game is a simple one and is played as a team. Both the players of a team will be given a string respectively. At the end of this game, every team is required find out the length of the longest string S such that the strings given to each of the team members is a subsequence of S andS contains no vowels. Help Harsh and Akshara in finding out the required length. Input: Input consists of a single line containing two space separated strings. Output: The length of the longest string that satisfy the given conditions. Constraints: 1 ? length of string ? 5000 Explanation The required string is "ng". if the constraint of the string S not containing vowels is removed, this becomes the classical Longest Common Subsequence (LCS) problem. For readers who are not familiar with LCS problem, they are encouraged to go through the following link which explains the problem as well to how to come up with the solution. http://en.wikipedia.org/wiki/Longest_common_subsequence_problem One can see that the LCS of the input two strings can never contain any vowels, hence, it is redundant to have vowels in the original string. Now, if we remove the vowels from the input strings, the problem is to find the length of the LCS of the edited strings. One can use the same approach described in the above wiki link to implement the solution.

course: C Srbject Code: Q. Art Chefs new hobby is painting, but he learned the fact that its not easy to paint 2D pictures in a hard way, after wasting a lot of canvas paper, paint and of course time. From now on, he decided to paint 1D pictures only. Chefs canvas is N millimeters long and is initially all white. For simplicity, colors will be represented by an integer between 0 and 105. 0 indicates white. The picture he is envisioning is also N millimeters long and the ith millimeter consists purely of the color Ci. Unfortunately, his brush isnt fine enough to paint every millimeter one by one. The brush is 3 millimeters wide and so it can only paint three millimeters at a timewith the same color. Painting over the same place completely replaces the color by the new one. Also, Chef has lots of bottles of paints of each color, so he will never run out of paint of any color. Chef also doesnt want to ruin the edges of the canvas, so he doesnt want to paint any part beyond the painting.

course: C Spbject Code: Q. Sherlock Homes There is a mysterious temple in Mysteryland. The door of the temple is always closed.lt can only be opened by a unique procedure.There are two boxes and N items outside the temple.Sherlock homes visits the temple many times.Each time Sherlock holmes visits the temple,the number of items N outside the door of the temple is changed but each time he anyhow manages to know the cost of those N items.The door of the temple can only be opened if those "N items" are distributed in those two boxes such that the sum of cost of items in one box is equal to the sum of cost of items in other box.Sherlock homes is trying to do such a distribution so as to open the door of the temple.you have to tell whether the door the temple can be opened or not. INPUT the first line contain the number of test cases i.e the number of time sherlock homes visits the temple. Next lines contains the description of those test cases.For the first line contain number of items "N".The second line contains cost of those N items. OUTPUT output "YES" if the door of the temple
can be opened otherwise output "NO".

course: C Stibject Code: Q. Selection Sorting Selection sort is based on the following idea: Selecting the largest array element and swapping it with the last array element leaves an unsorted list whose size is 1 less than the size of the original list. If we repeat this step again on the unsorted list we will have an ordered list of size 2 and an unordered list size n-2. When repeat this until the size of the unsorted list becomes one , the result will be a sorted list. Write a program to implement this algorithm.

Course: C Srbject Code: Q. Array Mode Write a program to find the mode of the elements in the array. The mode in a list of numbers refers to the list of numbers that occur most frequently. It is important to note that there can be more than one mode and if no number occurs more than once in the set, then there is no mode for that set of numbers. Input and Output Format: Input consists of n+1 integers where n corresponds to the number of elements in the array. The first integer corresponds to n and the next n integers correspond to the elements in the array. Refer sample input and output for formatting specifications. Assume that the maximum number of elements in the array is 20. Assume that in the input dataset there is 1 mode or no mode at all. All text in bold corresponds to input and the rest corresponds to output. Source Code #include #lnc|ude lnt ‘createArray(int); void readElement(lnt,int '); void arrayMode(int,lnt ’); lnt main() f lnt 'a,n; //printf("Enter the number of elements in the arrayln"); scanf("%d".&n): a=createArray(n); readEIement(n,a); printt("The mode of the array ls"); arrayMode(n,a); retum O; l

Course: C Srbject Code: Q. UPPER TRIANGULAR MATRIX An upper triangular matrix is a square matrix in which all the elements below the diagonal are zero. That is, all the non-zero elements are in the upper triangle: Write a C program to find whether a given matrix is an upper triangular matrix or not. Input Format: The input consists of (n’n+1) integers. The first integer corresponds to the number of rows/columns in the matrix. The remaining integers correspond to the elements in the matrix. The elements are read in rowwise order, first row first, then second row and so on. Assume that the maximum value of m and n is 5. Output Format: Print yes if it is an upper
triangular matrix . Print no if it is not an upper triangular matrix Source Code #include #lnclude int "createArray(int); void getE|ements(int",lnt); void triangu|arMatrix(int”,int); int main() ( Int "a,n; scanf("°/<>d".8tn)Z a=createArray(n); getElements(a,n); triangularMatrh(a,n)2 retum 0; l int "'createArray(int n) ( lnt i.“a; a=(Int' )malloc(n*sizeof(int')): for(i=0;i ( break; l else lf(('('(a+|)+j))|=0) l printf("no"): retum: l l l printf("yes"): l Sample Input
