Note that the limit for the number is <= 10^1e5. The largest value that can fit in a long long variable is 1e18 which is still too small on the limit.

    Thnx for the reply but I still don't get it....long long int can hold value upto 2^32 digits right? Here the largest length of the number could 1e5 so how come too small? Plz explain.

      $$$2^{31} -1$$$ is the maximum value of int, not the amount of digits. long long (or long long int, those two are identical) has a $$$2^{63} -1$$$ maximum value, but that doesn't still get close to $$$2^{32}$$$ digits. $$$2^{32}$$$ full decimal digits is equivalent to over 1.6 gigabytes, this is more than we can set as the memory limit for most problems.
