Hi,
On the contest time, I’ve submitted this problem many times, but got WA every times… 
Would anybody please tell me, for which case my code is failed ??? Here is my ideone code
I know that, in codechef/codeforces there is only one case per file… but I always do so in both of the site… And they become accepted too, if I don’t make any logical error…
In my code, is it only problem which make me more than 20 submission ???
i just edited that part…and it got AC…mostly the test file had some stray inputs at the end…they almost always have…hence u must follow the input specification that is provided in the problem description!!!
humm… you are right…
My code is accepted now… How silly thing that is !!!
Anyway, would you please tell me, what is the exact way to clear map with pair ??? Is it like normal mapping( e.g. map_name.clear()) ??
ya…it is the same!!!
