goal, return indices of the two numbers such that they add up to goal. We assume that each pair
of input array and goal has one and only one solution, and you cannot use the same element twice.
Please return the answer in an increasing order.
Example 1:
• Input: array = [2,2], goal = 4
• Output: [0,1]
• Explanation: Because array[0] + array[1] = 4, we return [0, 1].
Example 2:
• Input: array = [2,3,11,15], goal = 5
• Output: [0,1]
• Explanation: Because array[0] + array[1] = 5, we return [0, 1].
