Write an expression that executes the loop body as long as the user enters a non-negative number.
Note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds and report "Program end never reached." The system doesn't print the test case that caused the reported message.
Sample outputs with inputs: 9 5 2 -1
Body Body Body Done
User_num = int(input())
while User_num >= 0:
print("Body")
User_num = int(input())
print("Done")
