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 93, the output is:

93 92 91 90 89 88 

Ex: If the input is 77, the output is:

77 

Ex: If the input is not between 20 and 98 (inclusive), the output is:

Input must be 20-98 

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.

Must be in CORAL CODING, appropriate spaces no one has been able to help me
