write a function that outputs a vector of only the odd indices of the input vector if that input's length is odd. if the input's length is even, then output a vector of its even indices. So if you input os [1 2 3 4 5 6], then your output should be [2 4 6]; if your input i s[1 2 3 4 5 6] then you should output [1 3 5].

Done, now what? All joking aside what have you tried? A hint to start would look at the function mod(). Also i think your last odd length example is wrong.

Honestly I don't even know how to start the problem.

Start by looking at how to create functions then indexing arrays and my suggested mod() function.
