Problem Statement Minimum Moves to Equal Array Elements LeetCode Solution – Given an integer array nums of size n, return the minimum number of moves required to make all array elements equal. In one move, you can increment n – 1 elements of the array by 1. Example 1: Input 1: nums = [1, 2, 3] Output: …
Problem Statement The Count and Say LeetCode Solution – “Count and Say” asks you to find the nth term of the count-and-say sequence. The count-and-say sequence is a sequence of digit strings defined by the recursive formula: countAndSay(1) = “1” countAndSay(n) is the way you would “say” the digit string from countAndSay(n-1), which is then converted …
Problem Statement The Best Time to Buy and Sell Stock LeetCode Solution – “Best Time to Buy and Sell Stock” states that You are given an array of prices where prices[i] is the price of a given stock on an ith day. You want to maximize your profit by choosing …
Problem Statement In this problem, we are given an array of integers. Also, we are allowed to perform a certain set of operations on this array. In one operation, we can increment ” n – 1″ (all elements except any one) elements in the array by 1. We need to …
Problem Statement Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example nums = [-2,1,-3,4,-1,2,1,-5,4] 6 Explanation: [4,-1,2,1] has the largest sum = 6. nums = [-1] -1 Approach 1 (Divide and Conquer) In this approach …
Consider a sorted array but one index was picked and the array was rotated at that point. Now, once the array has been rotated you are required to find a particular target element and return its index. In case, the element is not present, return -1. The problem is generally …
In the Maximum Subarray problem we have given an integer array nums, find the contiguous sub array which has the largest sum and print the maximum sum subarray value. Example Input nums[] = {-2, 1, -3, 4, -1, 2, 1, -5, 4} Output 6 Algorithm The goal is to find …
Problem Statement In the “Maximum Subarray Sum using Divide and Conquer” problem we have given an array of both positive and negative integers. Write a program that will find the largest sum of the contiguous subarray. Input Format The first line containing an integer N. Second-line containing an array of …
