python programming help please (1 Viewer)

jon92 · Oct 31, 2012

been set a task of writing a piece of code but i seriously dont have a clue where to start or even how to do it. I study multimedia computing and fine with the website design/graphic design but cant get my head around this programming.

can anyone help please

1. Use pseudocode to implement an algorithm which searches for values in a given ange. It should fit the following description:

INPUT: An unsorted array A and two integers l and u
OUTPUT: TRUE if A contains an element which is both greater than l and less than u, FALSE otherwise

You should make a note of the algorithm’s time complexity using O-notation and show the pseudocode to a member of staff before implementing as a function.

2. Now consider the problem when the array is sorted. You should be able to improve on the efficiency of the algorithm by using a divide and conquer approach. Write pseudocode and give the time complexity of the algorithm using Big O notation. If there is time available you should implement the algorithm with code, although this is not essential.

What d'ya think I am? Some kinda Rocket Surgeon?

Or you could try http://users.csc.calpoly.edu/~jdalbey/SWE/pdl_std.html

I took one look at that and decided to wait for the interpreters to arrive.

Haha tell me about it I have not a clue

Do they not do that in lessons?

jon92 · Oct 31, 2012

Not really in my 1st year at uni we would work from lecture notes but this year it like they expect you to know it

1st year is supposed to get everyone up to speed, sounds like you're dropped in the deep end.

Did Java but never enjoyed it and dont remember any of it now... Not that it would help with Python!

Now, Monty Python I could help with!

It's tough only picked the course for the web design, graphic design, video editing and animation. Even had to do engineering maths which I don't understand why we need to do for a design course

Why not teach yourself those things Jon? I've done them all (well, I'm just going through Flash animation atm), and taught myself through stuff I downloaded, books etc. I'm no numero uno expert, but I sure as hell didn't need no psuedocodes, algorithms, or unsorted arrays!
It depends what you need it for and what level of expertise you require.

You would be better off learning html5 than flash houch!

Try this - might give you a heads up!

It's hard to teach myself programming because I don't actually have a clue where to start. All of the other things I have self taugh myself from video tutorials and books

Thanks Nick. I'll have a nose around to see what I can find on it.

I started in 1992 - way before Windows! - I used to use "basic" programming to write simple games etc. Very matchsticky effect in those days! Obviously massively improved since. If I'd kept it up, who knows where I might be today? I then went on to write my own webpages using total HTML code - no editors back then!

Houch,

if you want to do animations take a look at the jQuery library http://jquery.com there are a ton of plugins that will help you. Flash is dying especially now that android/windows phones no longer support it as the mobile market is the big growth area.

you all lost me in the first three words i'll stick with warcraft

Ah BBC Basic don't know how i did it but had to write a program for databases back in 83.

I still haven't come any closer to solving this question

try this tutorial site http://www.codecademy.com/tracks/python maybe they will have something that will help you

MatthewWallis · Nov 6, 2012

I've done C, C++, VB and Java programming but no python yet so I can offer a bit of help. The way I read the question is that you only need to create pseudo code for this? Therefore you don't need to code anything. Ask for help on what solution you need to come up with and create pseudo code and an algorithm for it but it says that implementing the algorithm with code is not essential so you probably won't have to code anything
