🧠 Solution 1: Optimal Two-Pointer Approach

The exact strategy used in coding interviews!

Time Complexity: `O(m + n)`

*Space Complexity:* `O(1)`

This method efficiently merges both sorted arrays *in place* without using extra space.


💡 *Solution 2: Easy Approach (Combine + Sort)*

A simple and clean alternative for beginners.

*Time Complexity:* `O((m+n) log(m+n))`
*Space Complexity:* depends on sorting algorithm

Great for understanding the concept before mastering the optimal solution.
