Given a linked list, determine if it has a cycle in it. Follow up: Can you solve it without using extra space? 题意:如何判断链表是否有环 这是一个经典的问题,后面还有追问: 如果有环,计算环的长度? 找到碰撞点的位置? 首先,如何找环,设计两个指针,分别从链表的头节点开始,... ...
[PAT]02-线性结构2 Reversing Linked List (25分) 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 = 4K=4, you...

For each case, output the resulting ordered linked list. Each node occupies a line, and is printed in the same format as in the input. Sample Input: 00100 6 4 00000 4 99999 00100 1 12309 68237 6 -1 33218 3 00000 99999 5 68237 12309 2 33218 ...

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.”...
will also discuss the removal of an entry from the head of a linked list. As in the previous post, I shall provide demonstrations of the topics within the debugger in an attempt to relate the information to a real-world problem. Despite the title, we won't be working in reverse...

Given a singly linked list L. Let us consider every K nodes as a block (if there are less than K nodes at the end of the list, the rest of the nodes are still considered as a block). Your job is to reverse all the blocks in L. For example, given L as 1→2→3→4→5→6→...
