就地数组重新排序？

就地数组重新排序？

使用mutating

indices

:(。看起来很难（请参阅稳定的就地mergesort）。

a = [8, 6, 7, 5, 3, 0, 9]indices = [3, 6, 2, 4, 0, 1, 5]for i in xrange(len(a)):    x = a[i]    j = i    while True:        k = indices[j]        indices[j] = j        if k == i: break        a[j] = a[k]        j = k    a[j] = xprint a
