PRG/211 Week 3 Lab 7.4 Loops: Countdown until matching digits
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:
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.
