🔥 LeetCode Weekly Contest 499 – Problem 2

Today we solve:
LeetCode 3914 – Minimum Operations to Make Array Non Decreasing

This is Problem 2 from Weekly Contest 499 held on 26 April 2026.

In this video, we solve this tricky greedy + math based problem using the most optimal contest approach.

💡 Concepts Covered:
✔ Greedy Strategy
✔ Right to Left Traversal
✔ Proper Divisor Observation
✔ Non-Decreasing Array Logic
✔ Contest Problem Solving
✔ Python Clean Code Solution

🧠 Main Idea:

We process the array from right to left.

If the current element is greater than the next element, we must reduce it using valid operations so that the array becomes non-decreasing.

The key observation is:
we should reduce the number in the smartest possible way using divisor-based operations to minimize total steps.

Instead of brute force simulation, we use mathematical observation + greedy optimization.

This problem is a strong example of contest-based pattern recognition.

⏱ Time Complexity:
Optimal Greedy Approach

💾 Space Complexity:
O(1)

This type of question is very important for improving contest intuition and fast observation skills.
