python实现的希尔排序算法实例

def shellSort(items):
  inc = len(items) / 2
  while inc:
    for i in xrange(len(items)):
      j = i
      temp = items[i]
      while j >= inc and items[j-inc] > temp:
        items[j] = items[j - inc]
        j -= inc
      items[j] = temp
    inc = inc/2 if inc/2 else (0 if inc==1 else 1)
a = [35, -8, 11, 1, 68, 0, 3];
shellSort(a)
print a # [-8, 0, 1, 3, 11, 35, 68]
