Write a C# program that display multiplication tables. The program lets the user input a number from a text box, then the user clicks "Show" button, then the multiplication table of the input number will be printed out, from 1 to 9, line by line in a output label. A check box called "Reverse" will be provided. If the check box is checked, the the multiplication table will be printed in reverse order (from 9 to 1). You MUST use "for loop" to create multiplication table.

Example: If the user input 3 and Reverse check box is/isn't checked, then the final result will be displayed as follows:

Not checked	Checked
3 x 1 = 3	3 x 9 = 27
3 x 2 = 6	3 x 8 = 24
3 x 3 = 9	3 x 7 = 21
3 x 4 = 12	3 x 6 = 18
3 x 5 = 15	3 x 5 = 15
3 x 6 = 18	3 x 4 = 12
3 x 7 = 21	3 x 3 = 9
3 x 8 = 24	3 x 2 = 6
3 x 9 = 27	3 x 1 = 3
