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

*  *  *
*  *  *
*  *  *
*******
   *
   *
   *
   *


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
code:

Solution by JSBN

code:

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
