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。只有分为两种情况...
A. length() B. arrayLength() C. size() D. lengthOfArray() 相关知识点: 试题来源: 解析 A。在 Java 中,获取数组长度的方法是数组名.length。length()在 Java 中可以用来获取数组长度。arrayLength()、size()、lengthOfArray()在 Java 中都不是获取数组长度的正确方法。反馈...

本次解题使用的开发工具是eclipse,jdk使用的版本是1.8,环境是win7 64位系统,使用Java语言编写和测试。 02 第一种解法 特殊情况:当数组中没有元素时,直接返回空list。 正常情况:先将数组排序,然后获取数组的第一个元素作为起始索引index,如果数组第一个元素不等于1,因为1≤a[i]≤n,所以需要先将前面缺的部分补...
