Answer 1

I just posted the solution, than I realised that I probably shouldn't solve your assignment. Anyways, here are a couple of tips for you:

1. You can use the function fliplr() to invert the elements in a (row) vector. (hint: reverse the alphabet)

2. If you do: [~, index] = ismember('abcd','ac'), than index will be: index=[1 3] (hint: the index of 'a' and c in the alphabet are the same as for z and 'y' in the reverse alphabet)
