Follow up for "Find Minimum in Rotated Sorted Array":What if duplicates are allowed? Would this affect the run-time complexity? How and why? Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might be…
Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. 这道寻找旋转有序数组的最小值肯定不能通过直接遍历整个数组来寻找,这个方法过于简单粗暴,这样的话,旋不…

Math 对象下包含 min() 和 max() 方法 用于确定一组数值中的最大值和最小值.这两个方法都可以接收任意多个数值参数. var max = Math.max(1,2,3,4,5,6); console.log(max); var min = Math.min(1,2,3,4,5,6); console.log(min); 而如果我们要取出数组中的最大值或最小值,该怎么做呢?(以取出数组中的最大值为例) 先看代码 var testArr = [1,2,3,4,5,6]; var max…

基本上都知道用MAX()/MIN()来求出所需的最大/最小值,但是只能查出那个最值的字段,而想查出整条记录或是对应的其他值却不行(SELECT MAX(grade), name FROM test;-- 不行的原因还没搞清楚,等以后清楚了再补上:>),现在只能用如下方法先代替着: SELECT * FROM (SELECT * FROM test ORDER BY grade ASC LIMIT 1) a; PS:子查询一定要给一个别名,否则会报错 好像自己傻了,子查询中都把结果查询出来了,但在…
