You are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Follow up:Could you do this in-place? 方法一:常规思路: 将图片分为 行数/2 层,然后一层层进行旋转,由外到里.在这个过程中,比较关键的是下标的处理.可从n=3时得出一定的规律.每次旋转时,分析替换的元素对的下标和行.列的关系.如 i=0.j=0时 1:[0]…

Given a list, rotate the list to the right by k places, where k is non-negative. For example:Given 1->2->3->4->5->NULL and k = 2,return 4->5->1->2->3->NULL. 这道旋转链表的题和之前那道Rotate Array 旋转数组 很类似,但是比那道要难一些,因为链表的值不能通过下表来访问,只能一个一个的…

Rotate an array of n elements to the right by k steps. For example, with n = 7 and k = 3, the array [1,2,3,4,5,6,7] is rotated to [5,6,7,1,2,3,4]. Note:Try to come up as many solutions as you can, there are at least 3 different ways to solve this pro…

Given an array of integers A and let n to be its length. Assume Bk to be an array obtained by rotating the array A k positions clock-wise, we define a "rotation function" F on A as follow: F(k) = 0 * Bk[0] + 1 * Bk[1] + ... + (n-1) * Bk[n-1]. Ca…

We are given two strings, A and B. A shift on A consists of taking string A and moving the leftmost character to the rightmost position. For example, if A = 'abcde', then it will be 'bcdea' after one shift on A. Return True if and only if A can becom…

找了好多资料,要么是IE可以用,但是谷歌不行,,还有就是两个都可以用的,图片大小显示不全.终于找到一个好一点的js,先贴一下代码. 1.rotate.js jQuery.fn.rotate = function(angle,whence) { var p = this.get(0); // we store the angle inside the image tag for persistence if (!whence) { p.angle = ((p.angle==undefined?0:…

​给定一个链表,旋转链表,将链表每个节点向右移动 k 个位置,其中 k 是非负数. Given a linked list, rotate the list to the right by k places, where k is non-negative. 示例 1: 输入: 1->2->3->4->5->NULL, k = 2 输出: 4->5->1->2->3->NULL 解释: 向右旋转 1 步: 5->1->2->3-…

Given a linked list, rotate the list to the right by k places, where k is non-negative. Example 1: Input: 1->2->3->4->5->NULL, k = 2 Output: 4->5->1->2->3->NULL Explanation: rotate 1 steps to the right: 5->1->2->3-&g…

You are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Follow up:Could you do this in-place? 在计算机图像处理里,旋转图片是很常见的,由于图片的本质是二维数组,所以也就变成了对数组的操作处理,翻转的本质就是某个位置上数移动到另一个位置上,比如用一个简单的例子来分析: 1  2  3 7  4  1 4  5  6 -…

-moz-transform: rotate(5deg);-webkit-transform: rotate(5deg); 把图片旋转了5度.本以为轻而易举,可遇到了问题.在Fireofx中显示正常,但在webkit内核下的浏览器中,如Chrome和Safari,图片边缘会有很明显锯齿.也可以说是webkit抗锯齿的一个BUG.另外需要补充的一点,如果图片上级元素含有overflow:hidden;属性,则会让锯齿感更明显. 通过查找相关的资料,终于找到了解决办法.便是使用CSS3 3D tra…
