Problem Statement

Sort an array of integers (of any convenient size) into ascending order using Circlesort. In short, compare the first element to the last element, then the second element to the second last element, etc. Then split the array in two and recurse until there is only one single element in the array, like this: Repeat this procedure until quiescence (i.e. until there are no swaps). Show both the initial, unsorted list and the final sorted list. (Intermediate steps during sorting are optional.) Optimizations (like doing 0.5 log2(n) iterations and then continue with an Insertion sort) are optional. Pseudo code:

Let's start with the solution:

Source code in the coffeescript programming language

circlesort = (arr, lo, hi, swaps) ->
  if lo == hi
     return (swaps)

  high = hi
  low  = lo
  mid = Math.floor((hi-lo)/2)

  while lo < hi
    if arr[lo] > arr[hi]
       t = arr[lo]
       arr[lo] = arr[hi]
       arr[hi] = t
       swaps++
    lo++
    hi--

  if lo == hi
     if arr[lo] > arr[hi+1]
        t = arr[lo]
        arr[lo] = arr[hi+1]
        arr[hi+1] = t
        swaps++

  swaps = circlesort(arr,low,low+mid,swaps)
  swaps = circlesort(arr,low+mid+1,high,swaps)

  return(swaps)

VA = [2,14,4,6,8,1,3,5,7,9,10,11,0,13,12,-1]

while circlesort(VA,0,VA.length-1,0)
   console.log VA
