Solution: Zero Array Transformation I
Explore how to use a difference array to efficiently track query coverage and determine if an integer array can be transformed into a zero array. This lesson teaches you to manage range decrement updates and verify coverage sufficiency, improving problem-solving with frequency-tracking patterns.

Statement
Given an integer array nums of length n and a 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
