LeetCode | Minimum Number of Operations to Make All Array Elements Equal to 1 | C++ | Golang | Rust

In this video, I break down the LeetCode problem:

🔹 2654. Minimum Number of Operations to Make All Array Elements Equal to 1

You’ll understand the full reasoning behind the solution — from the mathematical insight to the brute-force approach — along with complete implementations in C++, Golang, and Rust.

This problem requires careful observation of GCD properties, and I walk through the logic step-by-step so you fully understand why the solution works.

📈 Time & Space Complexity

All the shown solutions follow:

Time Complexity:
T(N) = O(N³ × log(M))

Space Complexity:
S(N) = O(1)

Where:

N is the length of the input array

M is the maximum value in the array

You can optimize it to O(N² × log(M)), but I'll leave that as a challenge for you guys 😉.
