PROGRAMMING:Multiplication formula table
Please write a program to output the multiplication formula table of $$n times n $.
####Input format
> $$n$$
####Output format
>The multiplication formula table for $$n times n $.
####Sample input
```in
five
```
####Sample output
```out
1x1= 1
1x2= 2 2x2= 4
1x3= 3 2x3= 6 3x3= 9
1x4= 4 2x4= 8 3x4=12 4x4=16
1x5= 5 2x5=10 3x5=15 4x5=20 5x5=25
```
Note: the multiplication sign is a small letter X; The product field is 2 lattices wide (right aligned); There is one space between two columns; There are no spaces at the end of the line.
