Recently I came across some code snippets and it's full of mess, lacking fundamentals, lacking basic code separation... That made me to wonder why some developers aren't learning the basics before trying anything.
This is related to PHP's array .
An array has number of elements. All elements are integers and unique, which means there is no repetitive integers.
(e.g.) $foo = array(7, 5, 9, 13, 2, 8);
You have to sort the array, provided:
You should scan the elements only once. You're not allowed to compare the elements when sorting. (i.e., you're not supposed to use any comparison operators) Sorted resultant array may not be the source array.
How will you do that?
