    560 - Subarray Sum Equals K.

    Medium

    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.

    Example 1:

    Input: nums = 1,1,1, k = 2

    Output: 2

    Example 2:

    Input: nums = 1,2,3, k = 3

    Output: 2

    Constraints:

    • <code>1 <= nums.length <= 2 * 10<sup>4</sup></code>

    • -1000 &lt;= nums[i] &lt;= 1000

    • <code>-10<sup>7</sup><= k <= 10<sup>7</sup></code>
