题目: Reverse digits of an integer. Example1: x = 123, return 321 Example2: x = -123, return -321 分析: 乍看,好似是一个很简单的题目,只需要将整数从最低位起到最高位依次处理即可,但是,此题的关键在于如何处理溢出数据.我们知道,Integer类型数据的范围是: #define       INT_MIN         (-2147483647 - 1)          /* minimum (sig…

翻转32位无符号二进制整数 Reverse bits of a given 32 bits unsigned integer. For example, given input 43261596 (represented in binary as 00000010100101000001111010011100), return 964176192 (represented in binary as 00111001011110000010100101000000). Follow up:If…

题目 Given an input string, reverse the string word by word. For example, Given s = "the sky is blue", return "blue is sky the". Update (2015-02-12): For C programmers: Try to solve it in-place in O(1) space. click to show clarification.…

题目 Reverse a singly linked list. click to show more hints. Hint: A linked list can be reversed either iteratively or recursively. Could you implement both? 分析 反转链表. 一个简单的解法,既然反转该链表,我们把所有节点作为一个输入序列,按照头插法重新构造一个链表即可,它既是所给链表的反转结果. 题目所给提示还有另外两种方法解决,迭代和递归.…

题目 Reverse a linked list from position m to n. Do it in-place and in one-pass. For example: Given 1->2->3->4->5->NULL, m = 2 and n = 4, return 1->4->3->2->5->NULL. Note: Given m, n satisfy the following condition: 1 ≤ m ≤ n ≤…

题目 Given a linked list, reverse the nodes of a linked list k at a time and return its modified list. If the number of nodes is not a multiple of k then left-out nodes in the end should remain as it is. You may not alter the values in the nodes, only…

题目 Given a binary tree, return the bottom-up level order traversal of its nodes' values. (ie, from left to right, level by level from leaf to root). For example: Given binary tree {3,9,20,#,#,15,7}, return its bottom-up level order traversal as: 分析 与…
