Sum Mixed Values
Real data often arrives in a messy mix: some numbers are already integers, while others are stored as strings. Write sum_mix, which takes a list arr, converts every element to an integer, and returns the total sum. The strings inside the list contain only numbers, so they can be converted safely.
