325. Maximum Size Subarray Sum Equals k

Given an integer array nums and an integer k, return the maximum length of a subarray that sums to k. If there isn't one, return 0 instead.

Example 1:

Input: nums = [1,-1,5,-2,3], k = 3
Output: 4
Explanation: The subarray [1, -1, 5, -2] sums to 3 and is the longest.

Example 2:

Input: nums = [-2,-1,2,1], k = 1
Output: 2
Explanation: The subarray [-1, 2] sums to 1 and is the longest.

Constraints:

  • 1 <= nums.length <= 2 * 105

  • -104 <= nums[i] <= 104

  • -109 <= k <= 109
