Swap First and Last

An array called nums has already been created for you with the values {10, 20, 30, 40, 50}.

Your task is to swap the first element and the last element of the array, then print all elements on one line separated by spaces.

To swap two values, you need a temporary variable to hold one of them so it doesn't get overwritten. Here's the pattern:
1. Save the first element in a temp variable
2. Set the first element to the value of the last element
3. Set the last element to the value stored in temp

After swapping, the array should be {50, 20, 30, 40, 10}.
