OK, so runoff seems much easier than Tideman which is so far a fail for me. I did find a few things – Here’s some of the code.

This problem sucks! Frankly, I gave up and so far, failed! I say ‘so far’ because I may come back to this problem. I got frustrated and then annoyed and then bored. I couldn’t get the data structures straight in my head and was losing interest because really, I want to get out of CS50… Continue reading CS50 – Week 3 – Tideman

This one was easy. Perhaps I was supposed to use a fancier algorithm but this gets the job done. Here’s part. A lot of this was supplied as part of the problem statement. Had a stupid range error bug to find which took longer than the solution :(.

Here’s the concepts covered this week:

Here’s part of substitution. I found this easier actually than thinking of the decimal to binary conversion. A bit of fiddling and thinking regarding the case of the source text vs the key text.

OK, so here’s part of Bulbs. Done. Some annoying Decimal to Binary to research…. Note, the check was failing due to a debug printf I had in the output. Passed once I removed this. So, remove or comment out your debug statements!

So, here’s Caesar. This was annoying actually. Firstly, need to think about ASCII, characters and integer equivalents which I don’t really want to think about. That’s the thing with learning to code, or perhaps learning anything really. Unfortunately, it seems you have to practice and to practice, you have to do sample problems that give… Continue reading CS50 – Week 2 – Caesar
