Time complexity : O(n). Assume that n is the list's length, the time complexity is O(n) Space complexity : O(1) 2、递归法(Recursive) 分析: 假设我们的链表为:n[1]→…→ n[k-1]→ n[k]→ n[k+1]→…→ n[m]→ NULL 如果此时n[k+1]到n[m]已经完成反转,此时cur当前的位置为n...
if you are not, maybe you are a fresher and you will going to find about this very soon in your next technical interview. In the last article, I have shown youhow to use recursion to reverse a linked list, and today, I'll

As a more particular example, the content-identifying information may be transmitted over a slotted paging channel in the form of a linked list of content summaries. The list may start in one particular slot. This particular slot may be the same for all cells in an area controlled by the ...
