Leetcode Solutions

Detect Squares

Solution For Detect Squares Problem statement: You are given a stream of points in the plane where points[i] = [xi, yi]. Each point [xi, yi] represents a point on the 2D plane. We want to know how many squares can be formed by these points. A square is a quadrilateral with four equal sides and Detect Squares

Minimum Interval To Include Each Query

Solution For Minimum Interval To Include Each Query Problem statement: You are given an array of integers nums and an array queries, where queries[i] is a pair of indices (0-indexed). Find the minimum interval [l, r] such that for all queries[i], the subarray nums[l,r] contains A[queries[i][0]], A[queries[i][1]] and so on. A subarray (l,r) is called Minimum Interval To Include Each Query

Merge Triplets To Form Target Triplet

Solution For Merge Triplets To Form Target Triplet Problem Statement: You are given an array of the form target = [x, y, z] and an array of triplets triplets, where each triplet = [ai, bi, ci] describes the i-th triplet. You can select triplets and concatenate their elements (in the same order) if the elements Merge Triplets To Form Target Triplet

Hand Of Straights

Solution For Hand Of Straights The problem “Hand of Straights” on LeetCode is stated as follows: You are given an array of integers hand representing the cards you have. Each integer in hand represents a card of the corresponding value. The value of each card ranges from 1 to W where W is the maximum Hand Of Straights

Distinct Subsequences

Solution For Distinct Subsequences The Distinct Subsequences problem on LeetCode is a dynamic programming problem that asks to count the number of distinct subsequences of a string. Problem Statement: Given two strings s and t, return the number of distinct subsequences of s that are equal to t. A subsequence of a string is a Distinct Subsequences

Min Cost Climbing Stairs

Solution For Min Cost Climbing Stairs The Min Cost Climbing Stairs problem on Leetcode is a classic dynamic programming problem. It asks you to determine the minimum cost to climb to the top of a given staircase. The staircase has a certain number of steps, represented as an array of integers. Each element in the Min Cost Climbing Stairs

Swim In Rising Water

Solution For Swim In Rising Water The “Swim In Rising Water” problem on Leetcode asks us to find the minimum time required for a person to cross a grid of size n x n, where each cell in the grid represents the height of the ground. The person can move only UP, DOWN, LEFT, or Swim In Rising Water

Network Delay Time

Solution For Network Delay Time Problem Statement: You are given a network of n nodes, labeled from 1 to n. You are also given times, a list of travel times as directed edges times[i] = (u, v, w), where u is the source node, v is the target node, and w is the time it Network Delay Time

Min Cost To Connect All Points

Solution For Min Cost To Connect All Points Problem Statement: You are given an array points representing integer coordinates of some points on a 2D-plane, where points[i] = [xi, yi]. The cost of connecting two points [xi, yi] and [xj, yj] is the manhattan distance between them: |xi – xj| + |yi – yj|, where Min Cost To Connect All Points

Redundant Connection

Solution For Redundant Connection The Redundant Connection problem on LeetCode is a graph problem. The problem statement is as follows: In a directed graph with n nodes labeled 1 to n, there exists an edge connecting nodes u and v such that u != v and the edge is not already in the graph.
