parent() && parents() &&
closest()这三个方法都与沿着DOM向上导航有关,在由选择器返回的元素上方,匹配父元素或之前的祖先元素,但是每个方法都有各自独特之处:1.
parent()只匹配元素的直接父元素,他可以带一个选择器做参数,对于匹配符合某些条件的父元素非常有用。...

题目大意:先给定n个数字,现在要求算出这n个数字的两两之和保存到sum数组,然后在给定m个数,要求找到和每一个数最接近的sum[i];
挨个计算每个属于其他数之间的sum,然后排序;
查找时有两种方法:二分查找&&双向查找;当然二分查找的效率比后者高了很多,但是都能AC。
提供一条新思路,并不一定非要用二分。
双向查找:
#include
