Task

Show a loop which prints random numbers (each number newly generated each loop) from 0 to 19 (inclusive).

If a number is 10, stop the loop after printing it, and do not generate any further numbers.

Otherwise, generate and print a second random number before restarting the loop.

If the number 10 is never generated as the first number in a loop, loop forever.
