Leetcode 2295: Problem Discussion

Revision en2, by introart, 2022-06-05 09:23:57

This problem came in today's Leetcode Weekly contest 296.

The solution to this problem is pretty straightforward.
But my question is:
how can I solve the problem if the condition: operations[i][1] does not exist in nums is not necessarily true.

As an example

Input: nums = [1,2,3,4], operations = [[2,3],[3,1],[1,4]]
Output: [4,4,4,4]

Can anyone please help me?
