一、题目描述 Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. 二、分析 这题难度有,因为他默认的是数组中所有的元素是不同的。只...

String[] strArray = new String[]{"hello","Hello", "Hello kity", "hello kity","D","w","A","z"}; Arrays.sort(strArray ,String.CASE_INSENSITIVE_ORDER); System.out.println(Arrays.toString(strArray)); 1. 2. 3. 运行结果如下: [A, D, hello, Hello, Hello kity, hello kity, w,...
You may assume no duplicate exists in the array. 题解: 这道题是一道常见的二分查找法的变体题。 要解决这道题,需要明确rotated sorted array的特性,那么就是至少有一侧是排好序的(无论pivot在哪,自己画看看)。接下来就只需要按照这个特性继续写下去就好。以下就以伪代码方法来说明: ...

基于键值排序的键值对数组,使用二分查找(log n)检索key,也可根据index检索(log 1),add和remove都是o(n)。SortedList为了保持数组的排序,它会移动位于插入的元素位置之后的所有元素(使用Array.Copy()),由于每次的插入都会重新排序,导致插入时的性能很差,因此并不推荐使用SortedList排序一个数组。
