Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical.

Ex: If the input is:

the output is:

Ex: If the input is:

the output is:

Ex: If the input is:

or any number not between 20 and 98 (inclusive), the output is:

For coding simplicity, follow each output number by a space, even the last one.

Use a while loop. Compare the digits; do not write a large if-else for all possible same-digit numbers (11, 22, 33, …, 88), as that approach would be cumbersome for large ranges.
