For the Dhapu and the Big Sums

Problem code: ARHN04

my solution runs on your IDE and gives correct anwer on the various input but isn’t accepting solution on submission page.??? I think so there is some error in your system.

@jain_mj i guess you might be using an integer array for the calculations if so then you will get wrong answer because operands size is 10^200 and c/c++ cannot handle such big numbers.

since it is an ongoing contest i cannot give you hints but i can suggest you to search on google how to handle such big numbers in c/c++.

but sir I have checked it on the IDE of code chef and it is giving me correct solutions. I have checked even for the no with more than 50 digits and is giving correct result but it didn’t accepted my solution on the problem page

check your solution on the corner cases…

Sir, sorry but I couldn’t get it ,what does the corner cases mean???

Corner cases refer to the boundary values of input. Ex, if your program needs input of variable x and x lies in the range 0 to 100, then check for x=0,1,99,100. You may also like checking fr x=50(the middle value). For multiple inputs test for all possible combinations.
