1749. Maximum Absolute Sum of Any Subarray

https://leetcode.com/problems/maximum-absolute-sum-of-any-subarray

Description

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
