We have given an array of integer, q number of queries. Where each query contains three integers, which defines a type of query. This means if we have given 0 it means we have to find the probability of choosing an odd number in the given range. Where the range …
The problem “Find number of pairs in an array such that their XOR is 0” state that supposes, we have given an array of integers. The problem statement asks to find out the number of pairs present in an array, which has the pair Ai XOR Aj = 0. Note: …
Problem Statement The problem “Newman-Conway Sequence” states that you are given an input integer “n”. Then you need to print first nth element of the Newman-Conway Sequence. Example n = 6 4 n = 10 6 Explanation Since the output elements represent the sixth and tenth element of the Newman-Conway …
Problem Statement The problem “Find whether a subarray is in form of a mountain or not” states that you are given an integer array and a range. The problem statement asks to find out whether the sub-array formed between the given range is in form of a mountain form or …
Problem Statement The “Friends Pairing Problem” states that there are N friends. And each them can remain single or be paired up with each other. But once a pair is made, those two friends can not take part in pairing. So, you need to find the total number of ways …
Problem Statement The problem “Distance of nearest cell having 1 in a binary matrix” states that you are given a binary matrix(containing only 0s and 1s) with at least one 1. Find the distance of the nearest cell having 1 in the binary matrix for all the elements of the …
Problem Statement “Count subarrays having total distinct elements same as original array” states that you are given an integer array. The problem statement asks to find out the total number of sub-arrays that contain all distinct elements as present in an original array. Example arr[] = {2, 1, 3, 2, …
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 We are given a matrix of size “n x m”, and we need to collect maximum points in a grid using two traversals. If we are standing at cell i,j then we have three options to go to cell i+1, j or i+1, j-1or i+1, j+1. That is …
Problem Statement Given a complete Binary Search Tree, write an algorithm to convert it into a Min Heap, which is to convert BST to Min Heap. The Min Heap should be such that the values on the left of a node must be less than the values on the right …
