Try input:

Code: Select all

1
( ( 1000000.01 / 1000000.00 ) * 1000000.0 )

AC output:

Code: Select all

1000000.01

I solved it using a recursive descent parser where all intermediate values are kept as a double.

Thanks Brianfry, Got AC, Learned something new !!

Don't round until you print the final result.
Input: 1
( ( 0.01 / 100.00 ) * 100.0 )
AC output: 0.01

Fixed this issue, but again WA :(

WA again and again.Please help me to find my error or give me some test cases in which my code fails.

I am getting WA for missing 8 direction. Now AC

When a player stands next to one or more trap, he sense a draft but as he don't know from where the draft comes,so he cant move from his position. This is the main challenge.
