In this video, we’ll solve the "Valid Parentheses" problem from LeetCode, part of the Top Interview 150 series. The problem asks us to determine if a string of parentheses is valid. We'll dive into an efficient solution using the stack data structure in Python, explaining each step in detail. By the end of this tutorial, you'll understand: How to implement a stack to keep track of matching pare...

Find the Index of the First Occurrence in a String | Leetcode Top 150 Interview Given two strings needle and haystack, return the index of the first occurrence of needle in haystack, or -1 if needle is not part of haystack. Example 1: Input: haystack = "sadbutsad", needle = "sad" Output: 0 Explanation: "sad" occurs at index 0 and 6. The first occurrence is at index 0, so we return 0 #100daysofc...

238 . Product of Array Except Itself | Leetcode Fully Explained Given an integer array nums, return an array answer such that answer[i] is equal to the product of all the elements of nums except nums[i]. The product of any prefix or suffix of nums is guaranteed to fit in a 32-bit integer. You must write an algorithm that runs in O(n) time and without using the division operation. Example 1: Inp...

You are given an n x n 2D matrix representing an image, rotate the image by 90 degrees (clockwise). You have to rotate the image in-place, which means you have to modify the input 2D matrix directly. DO NOT allocate another 2D matrix and do the rotation. #Leetcode #CodingInterview #RotateImage #DataStructures #Algorithms #CodingTutorial #InterviewPreparation #TechInterview #LeetcodeSolutions

Given a sorted array of distinct integers and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order. You must write an algorithm with O(log n) runtime complexity. Example 1: Input: nums = [1,3,5,6], target = 5 Output: 2 Example 2: Input: nums = [1,3,5,6], target = 2 Output: 1 #Leetcode #CodingInterview #SearchInsertPosit...

Rotate Array Leetcode | LeetCode Top 150 | Brute Force Approach Given an integer array nums, rotate the array to the right by k steps, where k is non-negative. Example 1: Input: nums = [1,2,3,4,5,6,7], k = 3 Output: [5,6,7,1,2,3,4] Explanation: rotate 1 steps to the right: [7,1,2,3,4,5,6] rotate 2 steps to the right: [6,7,1,2,3,4,5] rotate 3 steps to the right: [5,6,7,1,2,3,4] Example 2: Input:...

(80) Remove Duplicate from sorted Array 2 | Medium Level Leetcode Top Interview Given an integer array nums sorted in non-decreasing order, remove some duplicates in-place such that each unique element appears at most twice. The relative order of the elements should be kept the same. Since it is impossible to change the length of the array in some languages, you must instead have the result be ...
