2つの合計問題

https://leetcode.com/problems/two-sum/ 問題

Example 1:
Input: nums = [2,7,11,15], target = 9
Output: [0,1]
Explanation: Because nums[0] + nums[1] == 9, we return [0, 1].


Example 2:
Input: nums = [3,2,4], target = 6
Output: [1,2]

Example 3:
Input: nums = [3,3], target = 6
Output: [0,1]

                if i!=j:
                    if nums[i] + nums[j] == target:
                        return [i, j]
