 Explanation of input data
===========================

1. Note
(1) Free format
    For input data, "free format system" is used. The following three data lists are the same. Divide each number by comma or blank(s).

   16        18           12                1
16 18 12 1
16,18,12,1


(2) Input file name
    Input file name should be "INPUT.DAT". The program reads the input data from "INPUT.DAT". If the name of your input data file is not "INPUT.DAT", rename the file before you run the program.


2. Example of data and its explanation
   The following is the explanation of "INPUT2.DAT".
