我想制作简单的排序算法.
如果输入"abcde",我想要下面的输出.你能告诉我算法吗？
arr[0] = "a"
arr[1] = "ab"
arr[2] = "ac"
arr[3] = "ad"
arr[4] = "ae"
arr[5] = "abc"
arr[6] = "abd"
arr[7] = "abe"
...
arr[n] = "abcde"
arr[n+1] = "b"
arr[n+2] = "bc"
arr[n+3] = "bd"
arr[n+4] = "be"
arr[n+5] = "bcd"
arr[n+5] = "bce"
arr[n+5] = "bde"
...
arr[n+m] = "bcde"
...
...
