1749 - Maximum Absolute Sum of Any Subarray.

Medium

You are given an integer array nums. The absolute sum of a subarray [numsl, numsl+1, …, numsr-1, numsr] is abs(numsl + numsl+1 + … + numsr-1 + numsr).

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:

  • 1 <= nums.length <= 105
  • -104 <= nums[i] <= 104
