# 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`
