Q: My program gets WA/TLE/RE with G++/GCC, but it's AC with C/C++ (or vice versa)!

A: It's probable that some tiny bugs hide in your AC code but due to compiler factors they doesn't take visible effect. It's recommended that you revise your code to fix the bugs. Another possible cause is the differences in default settings of code generation of compilers. For example, the stack size of programs compiler by VC is larger than that of those compiled by GCC/G++. Then a program relying on extremely deep recursion may possibly fail with GCC/G++. If you strongly believe (with sufficient evidence) it's caused by bugs of the compiler, please let us know.

　

Q: My program gets TLE with C/C++ but AC with GCC/G++! I'm sure there can't be any bugs in it.

A: Tests show that loops run much faster when compiled by GCC/G++ than by VC. The STL of G++ is also faster than that of VC. So when you are frustrated by such TLE's you may try using GCC/G++. Perhaps they may earn you an AC. Still we recommend you get AC with a more efficient code. If you strongly believe the time limit (whether total time limit or case time limit) for a problem is much too tight, please also let us know.
