Time Limit Exceeded even if I use string multiplication method. So what is the worst case number here? Can anyone help? Can the problem be solved with the recursion method?

java users try to input numbers as strings and then make a biginteger variable with the help of "new" and pass that string as argument to the constructor

In python it is really easy. but in c++ it is little bit complicated.

What does this statement actually mean? "Text grouped in [] does not appear in input file"

For Java users, remember to use BufferedReader and StringTokenizer instead of Scanner because Scanner is too slow. Scanner gave me TLE while BufferedReader is accepted :)
