I think one of these advices will help you:
1. Replace: cin/cout -> scanf/printf.
2. Add line "ios_base::sync_with_stdio(0);" at the beggining of your code and replace all scanf/printf to cin/cout

    Thank your tips, but i think cin is need replace to scanf, cout is unnecessary beacause the result is a string with length 2*n-2 ( it's small to affect the excution time ). :D

      I advise you to not use cin and scanf in one code, because it will work slowly
