# 0985. Sum of Even Numbers After Queries

https://leetcode.com/problems/sum-of-even-numbers-after-queries

## Description

You are given an integer array `nums` and an array `queries` where `queries[i] = [vali, indexi]`.

For each query `i`, first, apply `nums[indexi] = nums[indexi] + vali`, then print the sum of the even values of `nums`.

Return _an integer array_ `answer` _where_ `answer[i]` _is the answer to the_ `ith` _query_.

**Example 1:**

```
**Input:** nums = [1,2,3,4], queries = [[1,0],[-3,1],[-4,0],[2,3]]
**Output:** [8,6,2,4]
**Explanation:** At the beginning, the array is [1,2,3,4].
After adding 1 to nums[0], the array is [2,2,3,4], and the sum of even values is 2 + 2 + 4 = 8.
After adding -3 to nums[1], the array is [2,-1,3,4], and the sum of even values is 2 + 4 = 6.
After adding -4 to nums[0], the array is [-2,-1,3,4], and the sum of even values is -2 + 4 = 2.
After adding 2 to nums[3], the array is [-2,-1,3,6], and the sum of even values is -2 + 6 = 4.
```

**Example 2:**

```
**Input:** nums = [1], queries = [[4,0]]
**Output:** [0]
```

**Constraints:**

* `1 <= nums.length <= 104`
* `-104 <= nums[i] <= 104`
* `1 <= queries.length <= 104`
* `-104 <= vali <= 104`
* `0 <= indexi < nums.length`
