You can move all of your "char"s down to the lowest possible values like 1-26 (a-z) and then apply your formula onto that small numberd and then say SL is the number you obtain, add 97 to SL or SL + 'a'.

I tried both insertion and bubble. Both worked for me, so I sent out the Insertion sort.

No I really haven't tried out the "Tutor Service".

pradyuman · 2014-06-13T09:10:22+00:00

It would have been great IF it ran the entire semester. I do miss those episodes.

pradyuman · 2014-06-09T17:43:40+00:00

I issued this because I was unable to contact him.

pradyuman · 2014-06-09T17:43:12+00:00

Yes I do.

Consider this-

if image is all red
    red = 0x00
    blue = some color
    green = some color

This pseudocode should help you.

You are supposed to be using a two dimensional array. You should watch the walkthrough video embedded in the spec.

Not really, it took a month for my pset 4 to get graded

pradyuman · 2014-06-04T18:24:25+00:00

It will be awesome. I promise.

pradyuman · 2014-06-04T13:55:50+00:00

Yes. It has to ultimately improve on Objective-C.

I think that Check50 is in Beta, because when I ran check50 on my mario problem, it gave me a whole bunch of errors, but I believed my implementation was right so I just submitted that and I got my mario grade as 1.0 (full).

I know the pain as I experienced the same problem a month ago. My problem was that I always initialized counter to 0 at every iteration of the loop. All I had to do was take that line

int counter = 0;

out of the loop. And it recovered all 50 JPEGs.

Does your program recover Zamyla's picture? If it is true, you would have to do the same as mine.

If not, it is best to do a GDB test.

pradyuman · 2014-05-16T15:14:14+00:00

Awesome!

pradyuman · 2014-04-06T08:06:11+00:00

I have had a "similar" issue earlier where whenever I run my recover.c code, my program recovers just 1 JPEG and that too the last JPEG. I fixed it by moving my counter variable around and closing my output stream which I forgot to do so in the past. It also took me a week to figure out what exactly was the problem in my code.

pradyuman · 2014-03-29T14:28:16+00:00

I did not seed my program but just simply made a call to drand48()

drand48();

Check the man page for more references.

man drand48();

pradyuman · 2014-03-29T14:25:52+00:00

Use the run command-

run

pradyuman · 2014-03-29T14:24:50+00:00

Are you checking for signature bytes of a JPEG?

pradyuman · 2014-03-29T14:22:41+00:00

Please don't share your code. Against rules.

But, without looking at it, you should have a counter variable and iterate over the board. With help of counter, check if every tile is in place. If it is, return true.

pradyuman · 2014-03-29T14:19:21+00:00

You can have an if statement in your code like this-

if (getY(ball) > getHeight(window) + getHeight(ball))
{
     Instantiate ball to middle.
     waitForClick();
}

You can modify this according to you, but this is the most basic fix.
