i got some homework i have no idea how to solve.
so, if you can help me out a bit, that would be great.
i'm not asking you to solve it for me, of course.
** No loops or pointers allowed.
i need to write a function that gets 2 arrays of integers and their sizes and returns the amount of numbers repeating.
will return 2 (for 5 and 1);
int intersect (const int arr1,const in arr2,int size1,int size2,....);
(it's allowed to use more arguments in the function).
Loops - Not allowed (for,do,while)
side functions are allowed.
every function that assists this one, must be recursive.
assume the length of each array is 20 at most.
guys, i don't even have a clue where to begin
any kind of advice would be appritiated!
