Need help with the logical error in my code for BUGCAL

general

I think I couldn’t get the problems constraint right, although I partially solved the problem, got 30 pts. But I am not sure what is the logical error here. Any java wizard here to help?

The problem doesnt mention it in the statement but when outputting the answer we have to remove leading zero’s which is not done in this code

You should have read the comments .

test case 10001 90009

correct ans : 0 not 00000

The problem was with the leading zeros . I too solved the problem but didn’t knew that leading zeros needs to be removed.
DO CHECK COMMENT SECTION DURING CONTESTS !! IT HELPS.

44 64

for this it’s showing:08

it’s should show:8

Hope it helps…

To answer in simple way…when two inputs like 555,555 are given,your code prints 000.Actually it is expected to print 0. That’s the problem.
