Write a function that accepts a vector of positive integers (not to be checked) and returns the vector when all the double digits are listed at the beginning of the vector and all odd numbers are registered at the end of the vector after the pair. Do not use loops.

can some one help please

As soon as you show us what you've done so far and which part is causing you problem.

Without any demonstration of effort on your part, not really.

[Jan]

I agree with Guillaume: This sounds like a homework question. Then please post, what you have tried so far and explain the remaining problems.

I agree with Guillaume and Jan, you should explain a bit more of your problem. I'm not going to write the function, but here are some hints on how to get started:

sort to get the order right

mod to find even / odd numbers. see also here.

if you need further assistance, please give us an example of input and expected output and of course your work so far.
