Given a n × m binary matrix, count the number of sets where a set can be formed one or more same values in a row or column. Examples:...
Given two 2D binary arrays, a[][] and b[][] both of size M*N, the task is to pair each row in the array a[][] with any row in the array b[][] such that the total score can be maximized and the score for each pair is calculated as the total indexes at which values of both rows are identical....
Given an array A[] consisting of decreasing permutation of N numbers, the task is to sort the array using triple swaps. If it is not possible to sort the array then print -1....
Given two integers N and K, the task is to calculate the minimum number of adjacent swaps of digits required to make the integer N divisible by K....
Given two integers A and B, representing the count of objects of two different types, and another integer N which represents the number of shelves, the task is to place all objects in the given N shelves abiding by the following rules:...
