The problem “Find subarray with given sum (Handles Negative Numbers)” states that you are given an integer array, containing negative integers as well and a number called “sum”. The problem statement asks to print the sub-array, which sums up to a given number called “sum”. If more than one sub-array …
The problem “Length of the largest subarray with contiguous elements” states that you are given an integer array. The problem statement asks to find out the length of the longest contiguous sub-array of which elements can be arranged in a sequence (continuous, either ascending or descending). The numbers in the …
The problem “Count number of triplets with product equal to given number” states that we are given an integer array and a number m. The problem statement asks to find out the total number of triplets of with product equals to m. Example arr[] = {1,5,2,6,10,3} m=30 3 Explanation Triplets …
Suppose, you have an array of integers. The problem “Maximum difference between first and last indexes of an element in array” asks to find out the difference between the first and last index of each number present in an array such that the difference is being maximum of all. Example …
the problem “Find any one of the multiple repeating elements in read only array” states that suppose you are given a read-only array of size (n+1). An array is containing the integers from 1 to n. Your task is to find out any one of the repeated elements in the …
The problem “Find elements which are present in first array and not in second” states that you are given two arrays. Arrays consist of all the integers. You have to find out the numbers which will not be present in the second array but present in the first array. Example …
The problem “Check for Palindrome after every character replacement Query” states that suppose you are given a String and no. of Queries, each query has two integer input values as i1 and i2 and one character input called ‘ch’. The problem statement asks to change the values at i1 and …
The problem “Difference between highest and least frequencies in an array” states that suppose that you have an integer array. The problem statement asks to find out the maximum difference between the highest frequency and lowest frequency of two distinct numbers in an array. Example arr[] = {1, 2, 3, …
The problem “Find four elements that sum to a given value (Hashmap)” states that suppose, you have an integer array and a number called sum. The problem statement asks to determine if four elements present in the array which sums up to the given value “sum”. If true, then function …
The problem “Find all triplets with zero sum” states that you are given an array containing positive and negative number both. The problem statement asks to find out the triplet with the sum equal to 0. Example arr[] = {0,-2,1,3,2,-1} (-2 -1 3) (-2 0 2) (-1 0 1) Explanation …
