这是一项家庭作业。我想我已经设法弄明白了，但由于某些原因我的解决方案不起作用。
所以有一个包含6个节点的linked_list，我的答案是一个由空格分隔的6个整数的字符串。数字的范围只能是1到6.根据我的理解，这一切都归结为按节点值的降序对列表进行排序，答案是节点的顺序。
就我而言，恰好是：
node 6: 574
node 5: 385
node 4: 188
node 3: 675
node 2: 785
node 1: 952
降低顺序：1-> 2-> 3-> 6-> 5-> 4
虽然有时候，我会得到一组不同的节点值：
n1 -72
n2 17
n3 -93
n4 -68
n5 -127
n6 62
降低顺序：6-> 2-> 4-> 1-> 3-> 5
但出于某种原因，这6个数字都不起作用。我也按升序尝试了。我只收到这两组节点值中的一个。以下是我的代码的汇编转储：
