use any type of loop that would find you easy in solving the given machine problem

the input value is a non-negative number from 1 - 20,otherwise, an invalid message will be displayed prompting the user of invalid entry

the output is the row and column size of the number being entered
EXAMPLE

SAMPLE INPUT
Enter a number ( 1 - 20 ) - 5

SAMPLE OUTPUT : (5x5) matrix

1 @ @ @ 1
@ 2 @ 2 @
@ @ 3 @ @
@ 4 @ 2 @
5 @ @ @ 5

Look at the print out row by row. What goes on each row? What is the relationship between what goes on a row with the row number. Where on each row does the number go?

If you were to print any one row given the row number, where would you position the numbers for that row. For row 2 where on the row do the '2's go?

are you sure that the question is right? I think in sample output the 4th row should be like this: @ 4 @ 4 @

@ 4 @ 4 @

Have you worked out what goes on a line/row? For example: what goes on the first line?
