Solving LeetCode Problem 350. Intersection of Two Arrays II with TypeScript & JavaScript
GitHub: github.com/RuslanTsykaliak/LeetCode-TypeScript-JavaScript/tree/main/0350-intersection-of-two-arrays-ii
Welcome to my channel! In this video, we'll be tackling an easy yet interesting problem from LeetCode - Problem 350, titled "Intersection of Two Arrays II." This problem is a great way to practice array manipulation, sorting, and using the two-pointer technique.
🔹 Problem Statement:
Given two integer arrays, `nums1` and `nums2`, return an array of their intersection. Each element in the result must appear as many times as it shows in both arrays, and you may return the result in any order.
🔹 Solution Approach:
In this video, we'll solve this problem by sorting both arrays and then using a two-pointer technique to find the intersection. This method is efficient and easy to understand.
🔹 What You'll Learn:
1. How to sort arrays in TypeScript.
2. How to use the two-pointer technique to find common elements in sorted arrays.
3. Step-by-step explanation of the solution approach.
