The problem Check Array Formation Through Concatenation Leetcode Solution provided us with an array of arrays. Along with that we are also given a sequence. We are then told to find if we can somehow construct the given sequence using array of arrays. We can arrange the arrays in any …
The problem Insert Interval Leetcode Solution provides us with a list of some intervals and one separate interval. Then we are told to insert this new interval among the list of intervals. So, the new interval might be intersecting with intervals that are already in the list, or it might …
The problem Combination Sum Leetcode Solution provides us an array or list of integers and a target. We are told to find the combinations that can be made using these integers any number of times that add up to the given target. So more formally, we can use the given …
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 …
The problem Find the Distance Value Between Two Arrays Leetcode Solution provides us two arrays arr1 and arr2. Along with the two arrays, we are provided with an integer n. Then the problem asks us to find the relative distance between the given two arrays. The relative distance is defined …
Problem Statement In this problem, we are given a list of string. We have to find out the characters that are common in all the strings. If a character is present in all strings in multiple times, then we have to output the character multiple times. Suppose, we have array …
The problem Minimum Absolute Difference Leetcode Solution provides us an unsorted array or vector containing some integers. We are required to find out all the pairs that have a difference equal to that of minimum absolute difference. The minimum absolute difference is the minimum value of absolute difference that can …
Problem Statement In this problem, we are given an array of strings. We need to print a list of all characters that appear in every string in the array(duplicates included). That is if a character appears 2 times in every string, but not 3 times, we need to have it …
Problem Statement In this problem, we need to find the difference between the product of digits and the sum of digits of a given positive integer. Example 1234 14 Explanation: Product = 4 * 3 * 2 * 1 = 24 and Sum = 4 + 3 + 2 + …
In the problem “Palindrome Linked List”, we have to check whether a given singly integer linked list is a palindrome or not. Example List = {1 -> 2 -> 3 -> 2 -> 1} true Explanation #1: The list is palindrome as all elements from the start and back are …
