个人心得:单纯用二分法一直超时,后面发现我的那种方法并没有节省多少时间,后面看了大神的代码,真的是巧妙, 俩个数组分别装a+b,c+d.双指针一个指向最后,从第一个开始想加,加到刚好大于0停止,再看是否存在和为0的情况. 很巧妙,因为此时i,j所指想加刚好大于0,因为是排完序的,所以i往后面走的时候,大于j的数相加一定大于0,所以卡的非常好: 就没有再指针跳转回去了,佩服! The SUM problem can be formulated as follows: given four list…

其实上一篇blog里已经贴了代码,简单解释一下吧: 1.showFooter: true,很重要,设置footer显示: $(cur_table).bootstrapTable({ url: '/etestpaper/getPaperQType', method: 'get', queryParams: {strParentID: parentid}, ajaxOptions: {strParentID: parentid}, showFooter: true, 2.在列中指定footerFor…

Given a binary tree containing digits from 0-9 only, each root-to-leaf path could represent a number. An example is the root-to-leaf path 1->2->3 which represents the number 123. Find the total sum of all root-to-leaf numbers. For example, 1 / \ 2 3…

The basic task is simple: given N real numbers, you are supposed to calculate their average. But what makes it complicated is that some of the input numbers might not be legal. A "legal" input is a real number in [-1000, 1000] and is accurate up…

求给出数的平均数,当然有些是不符合格式的,要输出该数不是合法的. 这里我写了函数来判断是否符合题目要求的数字,有点麻烦. #include <iostream> #include <cstdio> #include <algorithm> #include <string.h> using namespace std; ; bool islegal(char*str){ int len=strlen(str); ,; ;i<len;i++){ //if…
