The problem Unique Paths Leetcode Solution states that you are given two integers representing the size of a grid. Using the size of the grid, the length, and breadth of the grid. We need to find the number of unique paths from the top left corner of the grid to …
Suppose, we have an integer array. The problem statement “Maximum possible difference of two subsets of an array” asks to find out the maximum possible difference between the two subsets of an array. Conditions to be followed: An array can contain repeating elements, but the highest frequency of an element …
Problem Statement The problem asks to find “Inorder Successor of a node in Binary Tree”. An inorder successor of a node is a node in the binary tree that comes after the given node in the inorder traversal of the given binary tree. Example Inorder successor of 6 is 4 …
The problem “Check if a given array contains duplicate elements within k distance from each other” states that we have to check for duplicates in given unordered array within the range of k. Here the value of k is smaller than the given array. Examples K = 3 arr[] = …
Problem Statement The problem “Maximum product of an increasing subsequence” states that you are given an array of integers. Now you need to find out the maximum product you can achieve such that you multiply the elements of an increasing subsequence. The thing to note is that, we are not …
The problem “Form minimum number from given sequence” states that you are given some pattern of I’s and D’s only. The meaning of I stands for increasing and for decreasing we are provided with D. The problem statement asks to print the minimum number which satisfies the given pattern. We have …
The problem “Check in binary array the number represented by a subarray is odd or even” states that you are given a binary array and a range. The array consists of the number in the form of 0s and 1s. The problem statement asks to find out the number represented …
You are given a binary array, which consists of 0 initially and Q number of queries. The problem statement asks to toggle the values (converting 0s into 1s and 1s into 0s). After the Q queries performed, print the resultant array. Example arr[] = {0, 0, 0, 0, 0} Toggle(2,4) …
Problem Statement The problem “Count Primes in Ranges” states that you are given a range [left, right], where 0<=left<=right<=10000. The problem statement asks to find out the total number of prime numbers within the range. Assuming that there will be a large number of queries. Example left: 4 right:10 2 …
Problem Statement The problem ‘GCDs of given index ranges in an array” states that you are given an integer array and some range queries. The problem statement asks to find out the Greatest Common Divisor of the sub-array so formed within the range. Example arr[] = {10, 5, 18, 9, …
