#### Index of Target Number in List

The "Index of Target Number in List" code problem asks the reader to write a function that takes in a list of integers and a target number, and returns the index of the target number if it is present in the list, or -1 if it is not present.

#### Problem

```Given a list of integers and a target number, write a function that returns the index of the target number if it is present in the list, or -1 if it is not present.
Example input: [1, 2, 3, 4, 5], 3
Example output: 2```

#### Solution

This solution is in Python. Our A.I. can create solutions in multiple languages.
```def find_target(list, target):
for i in range(len(list)):
if list[i] == target:
return i
return -1

print(find_target([1, 2, 3, 4, 5], 3))
print(find_target([1, 2, 3, 4, 5], 6))

The solution is optimal because it uses a linear search algorithm.

```

A.I. Evaluation of the Solution

The candidate's solution is correct and uses a linear search algorithm, which is the most efficient way to search for an element in a list. The candidate's solution is complete and solves the problem.
