Array
Hash Table
Prefix Sum
Given an array of integers nums and an integer k, return the total number of subarrays whose sum equals to k.
A subarray is a contiguous non-empty sequence of elements within an array.
Examples
Example 1
Input: nums = [1,1,1], k = 2
Output: 2
Example 2
Input: nums = [1,2,3], k = 3
Output: 2
Constraints
1 <= nums.length <= 2 * 104
-1000 <= nums[i] <= 1000
-107 <= k <= 107
