LAB

$4\mathrm{.}52\mathrm{.}1$: LAB: Countdown until matching digits

Write a program that takes in an integer in the range $11-99($inclusive$)$ as input. The output of the program is a countdown starting from

the input integer until an integer where both digits are identical. End with a newline.

Ex: If the input is:

$93$

the output is:

$93$quad$9291908988$

Ex: If the input is:

$11$

the output is:

$11$

Ex: If the input is:

$9$

or any value not between $11$ and $99($inclusive$),$ the output is:

Input must be $11-99$

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 $(11,22,33,$l$,99),$ as that

approach would be cumbersome for larger ranges.
