#### Find two numbers in an array that add up to a given target number.

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.

#### Problem

```Given an array of integers, find two numbers that add up to a given target number.
Example input: [1, 2, 3, 4, 5], target=5
Example output: [2, 3]```

#### Solution

This solution is in Python. Our A.I. can create solutions in multiple languages.
```def find_two_numbers(array, target):

This function takes an array of integers and a target number.
It returns a list of two numbers that add up to the target number.

# Create a dictionary to store the numbers in the array as keys and their indices as values.
# This will allow us to look up the index of a number in the array in constant time.
# This is the optimal solution because it takes O(n) time to create the dictionary and O(1) time to look up a number.
# The total time complexity is O(n).
num_dict = {}
for i in range(len(array)):
num_dict[array[i]] = i

# Iterate through the array and check if the difference between the target number and the current number is in the dictionary.
# If it is, return the current number and the difference.
# This is the optimal solution because it takes O(n) time to iterate through the array and O(1) time to look up a number.
# The total time complexity is O(n).
for i in range(len(array)):
if target - array[i] in num_dict:
return [array[i], target - array[i]]

print(find_two_numbers([1, 2, 3, 4, 5], 5))```
