Solution: Zero Array Transformation I
Understand how to apply the difference array technique to solve the Zero Array Transformation problem. Learn to analyze query coverage on array indices and implement efficient range updates to verify if all elements can be decremented to zero. This lesson equips you with a method to handle range queries and evaluate conditions using prefix sums in linear time.

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
