1546. Maximum Number of Non-Overlapping Subarrays With Sum Equals Target

https://leetcode.com/problems/maximum-number-of-non-overlapping-subarrays-with-sum-equals-target

Description

Given an array nums and an integer target.

Return the maximum number of non-empty non-overlapping subarrays such that the sum of values in each subarray is equal to target.

Example 1:

**Input:** nums = [1,1,1,1,1], target = 2
**Output:** 2
**Explanation:** There are 2 non-overlapping subarrays [**1,1**,1,**1,1**] with sum equals to target(2).

Example 2:

**Input:** nums = [-1,3,5,1,4,2,-9], target = 6
**Output:** 2
**Explanation:** There are 3 subarrays with sum equal to 6.
([5,1], [4,2], [3,5,1,4,2,-9]) but only the first 2 are non-overlapping.

Example 3:

**Input:** nums = [-2,6,6,3,5,4,1,2,8], target = 10
**Output:** 3

Example 4:

**Input:** nums = [0,0,0], target = 0
**Output:** 3

Constraints:

• 1 <= nums.length <= 10^5

• -10^4 <= nums[i] <= 10^4

• 0 <= target <= 10^6
