Please provide g++ 3.4.2 or g++ 4.0, don't use g++ 4.3.2 please. g++ 4.3.2 has many problems for our ACMers, for example:
in previous g++ version, just #include, you can use any functions in these header files:
, but now, you have to include the correspond header file too.
And, in PKU online judge, many problems occured, because g++ 4.3.2 uses "%f" instead of "%lf".
