Hi, I'm about to start my university in september. I just wanted to know which course should I take? Computer Science(MEng) or Computer Science and mathematics with industrial experience? I mean if I take Computer science with mathematics will I be losing any edge over other students who study...

Homework Statement Ox-words are sequences of letters a and b that are constructed according to the following rules: I. The sequence consisting of no letters is an Ox-word. II. If the sequence W is an Ox-word, then the sequence that begins with a, followed by W and ending in b, written aWb...

Can u tell me the variations in this type of question that is what other questions can be asked in this context

So i should combine your argument plus mine and that will make the proof brief and rigorous

No what I meant was that when m-1 was left it will also be ending in either x or y. If it is ending in x then v can again swap it to end it in y and then again remove the y to get song of m-2 length. so like this v can keep on getting songs of length m-3, m-4, m-5 etc. In the end we will be song...

Ok... now if we remove the y(i.e song ending in a y) ,according to rule 4, of a song of length m then it will have length m-1 And if there is a song which ends in x we can use rule 3 to swap it and make it end in y so it will also have a length of m-1. So i think there will exist songs of all...

ok i will try to write the proof in the way you tell me. How abt the third part of the question?

Now because the first songs of 2m+2 end in y and the second song of 2m+2 end in x so they are different from each other.

First of all thank u for being rude. That has really helped. If there is a song k of length m than by rule 2 we have produced another song of length 2m + 2 so if there are k songs of length m then there will be k songs of length 2m+2. Now to produce other songs of length 2m+2 we have to swap...

I am unable to think in the form of variable to tell you the truth.

By rule 2 and 3 i have created another 2 songs, which are of length 2m+2...thats all i know :cry:

if there is a song k of length m then xkky and by rule 3 ykkx is also a song so we have produce another k song of 2m+2. Am i right?

Sorry but i don't know how to answer this question.
