I think i know how to solve this problem, but I have another broblem. How to input the text without using "string" variable. If I use "char a[MaxN][MaxN]", how to identify each string?(C++)I don't want to use <string.h> because sometimes it doesn't work on this server.
Thank's.

I used std::string to solve this problem.

But why do you afraid of using <string.h>? All standard functions of string.h are fully supported by the server.

stricmp is not supported :(
