This problem can be solved using a hashing approach. We can iterate through the array, adding each element to a hash table. Then, for each element, we can check if there is another element in the array that adds up to the target number. If so, we return the indices of the two numbers.
This is a great solution! The candidate has thought about the problem and come up with a solution that is both complete and efficient. The candidate has also taken the time to explain the thought process behind the solution.
