Z-lastchar

How to solve this task, bruteforce with string insertion is to slow?

with two lines of code :)

Well I don't know that two lines :D , I tryed for about and half an hour and couldn't think of solution :D

Have you used long long int?

Solved Thanks to Amtrix!
Admin, sorry for creating a new topic :(

don't apologize, that's what forum is for

Can somebody explain why the solution with 1<<N in code won't work ?

Bit shifting will only work with integer. Doesn't work with llint !

tnx

if you write 1, it is considered as int (long)

you can write (long long)1 << N
