Problem: Binary Subarrays With Sum

Medium
30 min
Understand and apply the sliding window technique to find the number of binary subarrays with a specified sum. This lesson helps you break down the problem, develop a clear solution approach, and implement it confidently in coding practice.

Statement

You are given a binary array, nums, and an integer, goal. Your task is to return the number of non-empty subarraysThis refers to a subarray, which is a contiguous part of the array. with a sum that meets the goal.

Constraints:

  • 11 \leq nums.length 3×104\leq 3 \times 10^4

  • nums[i] is either 00 or 11.

  • 00 \leq goal \leq nums.length
