Consider the task of rearranging all elements in an array so that the even numbers come first. Otherwise, the order doesn't matter. Ex:

$\backslash$table$[[$array:$,1,4,14,2,1,3,5,]]$

could be rearranged to

$\backslash$table$[[$array:$,4,2,14,6,1,5,3,23,1]]$

Try using coins and paperclips to think of an algorithm that solves this task by swapping elements. Then rearrange the following lines to describe it in pseudocode.

$i=0$

Swap elements at positions i and $j.$
