Problem Statement Next Permutation LeetCode Solution – A permutation of an array of integers is an arrangement of its members into a sequence or linear order. For example, for arr = [1,2,3], the following are considered permutations of arr: [1,2,3], [1,3,2], [3,1,2], [2,3,1]. The next permutation of an array of integers is the next lexicographically greater permutation of …
Problem Statement The Next Permutation LeetCode Solution – “Next Permutation” states that given an array of integers which is a permutation of first n natural numbers. We need to find the next lexicographically smallest permutation of the given array. The replacement must be in-place and use only constant extra space. …

We need to find the amount of water trapped after rain. Example: Input: height = [0,1,0,2,1,0,1,3,2,1,2,1] Output: 6 Explanation: Check …
Problem Statement 3Sum Closest LeetCode Solution – Given an integer array nums of length n and an integer target, find three integers in nums such that the sum is closest to target. Return the sum of the three integers. You may assume that each input would have exactly one solution. Input: nums = [-1,2,1,-4], target = 1 Output: …
Problem Statement The Kth Smallest Number in Multiplication Table Solution – states that you are given the multiplication table matrix of size m x n, where matrix[i][j] = i*j (1 indexed). For the given three integers m,n and k, we need to find the kth smallest element in the m …
Problem Statement We are given an array of integers. We need to return the integer which occurs more than ⌊N / 2⌋ time in the array where ⌊ ⌋ is the floor operator. This element is called the majority element. Note that the input array always contains a majority element. …
Problem Statement Given a sorted array, we need to find the majority element from the sorted array. Majority element: Number occurring more than half the size of the array. Here we have given a number x we have to check it is the majority_element or not. Example Input 5 2 …
