answer to the first test case should be 205
and for third test case should be 558
as question given as summing all digits except the digit mention as 'm'

Bryan Lambo on 16 Jan 2020

the problem means to exclude all numbers with the digit 'm'

so example n=20, m=5, you exclude numbers 5 and 15 as these contains the digit m=5.
