Solution: Zero Array Transformation I

Explore how to assess if an array can become a Zero Array after decrement operations defined by queries. Understand the use of a difference array and prefix sums to efficiently track coverage of indices by queries. This lesson helps you evaluate decrement opportunities and implement a solution with linear time complexity.

Statement

Given an integer array nums of length n and a 22D array queries, where queries[i] = [l_i, r_i], process each query sequentially as follows:

For each queries[i], select any subset of indices within the range [l_i, r_i] in nums and decrement the values at those selected indices by ...
