    1749 - Maximum Absolute Sum of Any Subarray\.

    Medium

    You are given an integer array nums. The absolute sum of a subarray <code>nums<sub>l</sub>, nums<sub>l+1</sub>, ..., nums<sub>r-1</sub>, nums<sub>r</sub></code> is <code>abs(nums<sub>l</sub> + nums<sub>l+1</sub> + ... + nums<sub>r-1</sub> + nums<sub>r</sub>)</code>.

    Return the maximum absolute sum of any (possibly empty) subarray of nums.

    Note that abs(x) is defined as follows:

    • If x is a negative integer, then abs(x) = -x.

    • If x is a non-negative integer, then abs(x) = x.

    Example 1:

    Input: nums = 1,-3,2,3,-4

    Output: 5

    Explanation: The subarray 2,3 has absolute sum = abs(2+3) = abs(5) = 5.

    Example 2:

    Input: nums = 2,-5,1,-4,3,-2

    Output: 8

    Explanation: The subarray -5,1,-4 has absolute sum = abs(-5+1-4) = abs(-8) = 8.

    Constraints:

    • <code>1 <= nums.length <= 10<sup>5</sup></code>

    • <code>-10<sup>4</sup><= numsi<= 10<sup>4</sup></code>
