转自Reversing a Linked List in Java, recursively There's code in one reply that spells it out, but you might find it easier to start from the bottom up, by asking and answering tiny questions (this is the approach in The Little Lisper): What is the reverse of null (the empty list)?
题目:Given a constantKK and a singly linked listLL, you are supposed to reverse the links of everyKK elements onLL. For example, givenLL being 1→2→3→4→5→6, ifK = 3K=3, then you must output 3→2→1→6→5→4; ifK = 4, you must output 4→3→2→1→5→6. //样本测试:...
Reverse Linked List 1,题目要求 Reverse a singly linked list. 翻转一个单链表。 2,题目思路 对于这道题,是单链表问题的一个非常经典的问题。一般来说,这个问题有两种解决办法:迭代与递归。 迭代: 迭代的方法相对来说比较简单。 我们首先定义一个节点,作为开始节点(NULL),然后在循环的过程中: 记录当前节点的...
Given a constantKand a singly linked listL, you are supposed to reverse the links of everyKelements onL. For example, givenLbeing 1→2→3→4→5→6, if K=3K = 3K=3, then you must output 3→2→1→6→5→4; if K=4K = 4K=4, you must output 4→3→2→1→5→6. Input Speci...

First, we need a linked list. Clear your workspace of unwanted xterms, sprinkle salt into the protective form of two parentheses, and recurse. Summon a list from the void.(defn cons [h t] #(if % h t)) “That’s not a list,” the interviewer says. “That’s an if statement.”...
