Canadian Computing Competition: 2003 Stage 1, Junior #1

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: $t$ ~t~, the height of the tines, $s$ ~s~, the spacing between tines, and $h$ ~h~, the length of the handle. For the example above we have $t = 3$ ~t = 3~, $s = 2$ ~s = 2~, and $h = 4$ ~h = 4~.

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

And why is this a J1 question when it's so hard??

More than half of all the submissions on this question are WAs

I had a lot of trouble on this question, but I think I finally figured it out. If you are having trouble with the last test case like I did, then make sure you check the values of t and s before printing a new line.

Yeah the most common problem is that the judge counts extra space appended at the end. To fix this problem what I did was that I would only append spaces to the end and if it was the last to add spaces I wouldn't add it. i + 1 != 3;

I sat staring at my screen trying to figure out how to do it

For test case #1 and #2, you have a presentation error when submitting, meaning you're outputting excess spaces after the final tine asterisk (e.g., * * * \n, which should be * * *\n); this could be remedied by printing a new line after all of your asterisks on a line are printed.

For the other three test cases, you are getting WAs (wrong answers): you are printing $S$ ~S~ tines with $S$ ~S~ spaces between them, instead of 3 tines with $S$ ~S~ spaces between them (this should be fixed first).

Thanks, I'm fixing it! :)

is this really j1 with a 49.2% success rate?1

A Low AC Rate doesn't necessarily have to mean anything

my code works in eclipse but not in DM:OJ? I'm pretty sure all the spacing is right

you should try using intellij

Its not that bad, just organize your code :) Did it in a couple min
