CCC 2003 Stage1: J1: Trident

-----------------------------------

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:
t the height of the tines
s the spaceing between tines
h the length of the handle

for above example we have t=3, s=2 and h=4

You are to write an interactive program to print a trident. Your program should accept as input the parameters t, s, and h, and print the appropriate trident. You can assume that t,s,h are each at least 0 and not larger then 10.

Sample input/output
Enter tine length:
4
Enter tine spacing:
3
Enter handle length:
2

var t : int 
var s : int 
var h : int 


put "Enter tine length:" 
get t 
put "Enter tine spacing:" 
get s 
put "Enter handle lenght:" 
get h 


for i1 : 1 .. t 

    for i2 : 1 .. 3 
        put "*" .. 

        for i3 : 1 .. s 
            put " " .. 
        end for 

    end for 

    put "" 

end for 

if s = 0 then 
else 
    for i4 : 1 .. (5 + s * 2) - 2 
        put "*" .. 
    end for 
    put "" 
end if 

for i5 : 1 .. h 
    for i6 : 1 .. s + 1 
        put " " .. 
    end for 
    put "*" 
end for
