    985 - Sum of Even Numbers After Queries\.

    Medium

    You are given an integer array nums and an array queries where <code>queriesi = val<sub>i</sub>, index<sub>i</sub></code>.

    For each query i, first, apply <code>numsindex<sub>i</sub> = numsindex<sub>i</sub> + val<sub>i</sub></code>, then print the sum of the even values of nums.

    Return an integer array answer where answer[i] is the answer to the <code>i<sup>th</sup></code> 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 nums0, the array is 2,2,3,4, and the sum of even values is 2 + 2 + 4 = 8.

    After adding -3 to nums1, the array is 2,-1,3,4, and the sum of even values is 2 + 4 = 6.

    After adding -4 to nums0, the array is -2,-1,3,4, and the sum of even values is -2 + 4 = 2.

    After adding 2 to nums3, 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:

    • <code>1 <= nums.length <= 10<sup>4</sup></code>

    • <code>-10<sup>4</sup><= numsi<= 10<sup>4</sup></code>

    • <code>1 <= queries.length <= 10<sup>4</sup></code>

    • <code>-10<sup>4</sup><= val<sub>i</sub><= 10<sup>4</sup></code>

    • <code>0 <= index<sub>i</sub>< nums.length</code>
