Solution: Zero Array Transformation I
Understand how to apply difference arrays and prefix sums to solve if it's possible to convert a given array into a zero array after a sequence of decrement queries. Learn to efficiently track coverage and validate each element's decrement opportunities within range queries.

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
