Evenly select N elems from array
- by ninuhadida
Hi,
I need to evenly select n elements from an array. I guess the best way to explain is by example.
say I have:
array [0,1,2,3,4] and I need to select 3 numbers.. 0,3,4.
of course, if the array length <= n, I just need to return the whole array.
I'm pretty sure there's a defined algorithm for this, been trying to search, and I took a look at Introduction to algorithms but couldn't find anything that met my needs (probably overlooked it)
The problem I'm having is that I can't figure out a way to scale this up to any array [ p..q ], selecting N evenly elements.
note: I can't just select the even elements from the example above..
A couple other examples;
array[0,1,2,3,4,5,6], 3 elements ; I need to get 0,3,6
array[0,1,2,3,4,5], 3 elements ; I need to get 0, either 2 or 3, and 5
