Once upon a time, in a village of coders, there lived a gardener named Prashant. He had two ways of planting flowers in his garden Greedy and Non

1. What Are We Talking About?The 132 pattern is a problem where we need to find a subsequence of three numbers in an array (nums[i], nums[j],&nbs

Situation:You are given a sorted array of integers where every element appears exactly twice, except for one element that appears only once.

In the world of computer science and mathematics, some problems are deceptively simple to describe but incredibly challenging to solve.One such problem is the&n

Greedy algorithm only applies to the optimization problem.Greedy algorithm makes the decision at every point choosing the local minimum or maximum depending on

Given the roots of two binary trees p and q, return true if the trees are equivalent, otherwise return false.Two binary trees

This problem check if a certain part of a tree is same tree as a given subtree.So before we solve this problem, we need to know how to check if two trees are sa

Given a binary tree, return true if it is height-balanced and false otherwise.A height-balanced binary tree is defined a

You are given an m x n grid where each cell can have one of three values:0 representing an empty cell,1 representing a fresh orange, or
