# [Solution] Number of Ways to Split Array solution leetcode

Number of Ways to Split Array solution leetcode – You are given a 0-indexed integer array `nums` of length `n`.

`nums` contains a valid split at index `i` if the following are true:

## [Solution] Number of Ways to Split Array solution leetcode

• The sum of the first `i + 1` elements is greater than or equal to the sum of the last `n - i - 1` elements.
• There is at least one element to the right of `i`. That is, `0 <= i < n - 1`.

Return the number of valid splits in `nums`.

Example 1:

```Input: nums = [10,4,-8,7]
Output: 2
Explanation:
There are three ways of splitting nums into two non-empty parts:
- Split nums at index 0. Then, the first part is , and its sum is 10. The second part is [4,-8,7], and its sum is 3. Since 10 >= 3, i = 0 is a valid split.
- Split nums at index 1. Then, the first part is [10,4], and its sum is 14. The second part is [-8,7], and its sum is -1. Since 14 >= -1, i = 1 is a valid split.
- Split nums at index 2. Then, the first part is [10,4,-8], and its sum is 6. The second part is , and its sum is 7. Since 6 < 7, i = 2 is not a valid split.
Thus, the number of valid splits in nums is 2.
```

```Input: nums = [2,3,1,0]
Output: 2
Explanation:
There are two valid splits in nums:
- Split nums at index 1. Then, the first part is [2,3], and its sum is 5. The second part is [1,0], and its sum is 1. Since 5 >= 1, i = 1 is a valid split.
- Split nums at index 2. Then, the first part is [2,3,1], and its sum is 6. The second part is , and its sum is 0. Since 6 >= 0, i = 2 is a valid split.
