Move Zeroes | LeetCode 283 Explained in C++ 🚀 | Two Pointer Approach | Easy Array Problem

In this video, we solve LeetCode 283 - Move Zeroes using a simple and beginner-friendly Two Pointer Approach in C++.

📌 Given an integer array nums, move all 0s to the end while maintaining the relative order of the non-zero elements.

Example 1

Input:

nums = [0,1,0,3,12]

Output:

[1,3,12,0,0]

Explanation:

Move all zeroes to the end while keeping the order of non-zero elements unchanged.

✅

Example 2

Input:

nums = [0]

Output:

[0]

✅

What You'll Learn

✅ Arrays

✅ Two Pointer Technique

✅ Swapping Elements

✅ In-Place Algorithms

✅ Beginner-Friendly DSA

Approach

1️⃣ Create a pointer k to track the position of non-zero elements.

2️⃣ Traverse the array.

3️⃣ Whenever a non-zero element is found, swap it with nums[k].

4️⃣ Increment k.

5️⃣ After traversal, all non-zero elements will be at the front and all zeroes at the end.
