// General : The program will get three numbers and and a code. If the code is 'U', the program will arrange the numbers from small to big. If the code is 'D', the program will arrange the numbers from big to small.
//
// Input   : A code and three numbers.
//
// Process : The program will check weather the code is 'D' or 'U', and it will arrange the numbers accoring to the code.
//
// Output  : Sort result.
