You are given an array of integers and a target value as the input. There are exactly two integers in the array which add up to the target value. You are required to return the indices of these 2 integers. Watch this video to learn 3 ways of solving this problem. You will learn a brute force solution, a solution using sorting, and a solution using Hash-map. Each of the solution has been explained with step by step animations and with a dry-run of the code so that it sticks in your mind forever. • 00:00 - Intro • 01:07 - Problem statement and description • 03:54 - Brute Force Method • 06:03 - Method 1: Using Sorting • 10:36 - Method 2: Using Hash-Map • 14:04 - Dry-run of code • 16:35 - Final thoughts • 📚 Links I talk about in the video: • Brute Force Method: • Brute Force algorithms with real life... • Quick Sort: • Quick Sort super easy explanation wit... • Time Complexity: • What is the Time Complexity of an Alg... • Actual problem on LeetCode: https://leetcode.com/problems/two-sum/ • Code on Github: https://github.com/nikoo28/java-solut... • Test cases on GitHub: https://github.com/nikoo28/java-solut... • 📘 A text based explanation is available at: https://studyalgorithms.com/array/lee... • 🔗 To see more videos like this, you can show your support on: https://www.buymeacoffee.com/studyalg... • 💻 Get Social 💻 • Follow on Facebook at: / studyalgos • Follow on Twitter at: / studyalgorithms • Follow on Tumblr at: / studyalgos • Subscribe to RSS feeds: https://studyalgorithms.com/feed/ • Join fan mail: http://eepurl.com/g9Dadv • #leetcode #programming #interview
