Input: nums = [3,4,5,6], target = 7
Output: [0,1]
Explanation:
Example 2:
Input: nums = [4,5,6], target = 10
Output: [0,2]
Example 3:
Input: nums = [5,5], target = 10
Output: [0,1]

Given an array of integers nums and an integer target, return the indices i and j such that nums[i] + nums[j] == target and i != j.
You may assume that every input has exactly one pair of indices i and j that satisfy the condition.
Return the answer with the smaller index first.
nums[0] + nums[1] == 7, so we return [0, 1].
2 <= nums.length <= 1000-10,000,000 <= nums[i] <= 10,000,000-10,000,000 <= target <= 10,000,000
