As you can see, it was well written, but when it was compiled, it took 0.078 seconds while i see fellow java coders clocking speed of 0.031, can you suggesting better classes to read inputs instead of the one i used, all other suggestions are highly welcome

It has no problem and can be accepted.

Yes, it was accepted but that is not the issue. The real issue is how i can optimize the code in such a way to clock 0.031 sec that others clocked. Thanks.

But I cant find the code which clock 0.031 by google. Can anyone help me?
