The divideParts method

The divideParts method takes an array of integer elements, upper int, and below int as parameters. The method sorts the elements in ascending order, as shown in the following code:

// divideParts methodfunc divideParts(elements []int, below int, upper int) int {  var center int  center = elements[upper]  var i int  i = below  var j int  for j = below; j < upper; j++ {    if elements[j] <= center {      swap(&elements[i], &elements[j])      i += 1    }  }  swap(&elements[i], &elements[upper])  return i}
