Complete the get_user_solution() function that takes a single string parameter problem_string. The function will:

1. Print the message "Enter your answer".
2. Use the problem_string as a prompt to obtain input from the user - their solution to the problem. You can assume that the user will always enter an integer value as the solution.
3. Return the user's solution.

Some examples of the function being called are shown below.

For example:

Test	Input	Result
solution = get_user_solution("25 + 8 = ") print("Your solution is", solution)	33	Enter your answer 25 + 8 = 33 Your solution is 33
problem_string = "13 - 6 = " print("Your solution is", get_user_solution(problem_string))	7	Enter your answer 13 - 6 = 7 Your solution is 7
