Solution: Zero Array Transformation I

Explore the solution to transforming an integer array into a zero array by processing given decrement queries. Understand how to use a difference array and prefix sums to track coverage efficiently, enabling you to check if all elements can be decremented to zero within query constraints.

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 ...
