Problem Statement “Count pairs from two sorted arrays whose sum is equal to a given value x” problem states that you are given two sorted arrays of integers and an integer value called sum. The problem statement asks to find out the total number of pair which sums up to …
Problem Statement You are given an array of integers, some numbers are repeated in it. The problem statement asks to print the number in the array in decreasing order according to their frequency that is to sort elements by frequency. Example arr[]={3,4,3,1,2,9,2,9,2,5 } 2 2 2 3 3 9 9 …
Problem Statement Suppose you have an array of integers of size n. The problem statement asks to find out the minimum number of subsets with distinct elements, that is subsets that can be formed which contain all the different/distinct elements from the array. Example arr[] = {2,4,6,2,1,4,2} 3 Explanation: {1, …
Problem Statement You are given an array of integers. The problem statement asks to find minimum difference between any two elements given in the array. Example arr[] = {11,1,6,8,20,13} 2 Explanation: Minimum difference between 11 and 13 is 2. arr[] = {19,14,80,200,32,29} 3 Explanation: Minimum difference between 32 and 29 …
