+// General : The program takes the last digits according to input
+//              from each number inputted.
+//
+// Input : how many numbers to take and input, and how many digits
+//          at least for the input.
+//
+// Process : the program gets input from user, then takes the
+//              last numbers according to input, and makes a char 
+//                matrix out of it.
+//
+// Output : numbers in a matrix looking form.
