What should be the expected output for number with all 9’s, say 999999?Is it 111111 or 100000 as we are inverting the digits?
And for a number like 20004567, what should be the output?
Chewbacca and number
For 999999 we should get 900000 because the digit can be inverted only and number of digits must not be changed.As if the leading 9 is inverted it will make it 0 which is equivalent to one less digit in the final answer and that must not happen .
for 20004567 we must have 20004432.
