Leetcode 2302. Count Subarrays With Score Less Than K - two-pointer sliding window method

Показать описание

A Python solution using two-pointer sliding window. The main idea is routine: for each index i, find the longest subarray ending at index i and satisfying the score bound condition. To check this condition, we track a partial sum state. Then the remaining is the routine check and update.

(Correction: at time 15:08, the sum shall be S + y + nums[r_0 + 1]; this does not affect the argument.)
