Leetcode 3818: Minimum Prefix Removal To Make Array Strictly Increasing

Jumping into LeetCode 3818: Minimum Prefix Removal To Make Array Strictly Increasing

In this video, we solve a neat array problem where you’re allowed to remove exactly one prefix (possibly empty) and need to find the minimum length to remove so that the remaining array becomes strictly increasing.

We’ll break down the intuition step by step—starting from understanding what “strictly increasing” really means, identifying where the array violates this condition, and efficiently finding the smallest prefix to remove. The solution is optimized to handle large inputs and avoids unnecessary brute force.

📌 What this walkthrough covers:
Observing patterns in strictly increasing arrays
Efficient scanning from the end
Edge cases (already increasing, single element left, negative values)
