Trident

문제

A trident is a fork with three tines (prongs). A simple picture of a trident can be made from asterisks and spaces:

*  *  *

In this example, each tine is a vertical column of 3 asterisks. Each tine is separated by 2 spaces. The handle is a vertical column of 4 asterisks below the middle tine.

Tridents of various shapes can be drawn by varying three parameters: $tt$, the height of the tines, $ss$, the spacing between tines, and $hh$, the length of the handle. For the example above we have $t=3t\; =\; 3$, $s=2s\; =\; 2$, and $h=4h\; =\; 4$.

You are to write an interactive program to print a trident. Your program should accept as input the parameters $tt$, $ss$, and $hh$, and print the appropriate trident. You can assume that $tt$, $ss$, $hh$ are each at least 0 and not larger than 10.
