Question
Given a list of integers, a batch of queries, and an integer limit, count how many queries select a range whose sum is strictly below the limit. Each query is a pair [l, r] with 0 <= l <= r < n, selecting elements l through r inclusive. Return the number of qualifying queries. Values may be negative. Example: values = [8, 2, 5, 1], queries = [[0, 1], [1, 3], [2, 3]], limit = 9 gives 2 — the range sums are 10, 8, and 6.
count_below_limit(values: list[int], queries: list[list[int]], limit: int) → int[[8,2,5,1],[[0,1],[1,3],[2,3]],9]out2State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.
