(11.11特供)Mobile Payment VS Cash:Are We Creating A One day a year ago I accidentally left my wallet in home and went out. All I found in my bag were keys and mobile phone. At that moment I thought :“Oh my god I'm screwed,what should I do ?”But Then I ride a mobike to a near shopping mall ,bought a beautiful skirt . Obviously, cash is falling out of fashion. So will it disappear forever? I guess not. Cash may become less popular, but it will remain with us forever. Why?

Presentation skills

Presentation skills There are four useful tips that we could use when we begin to prepare a presentation. A good understand of your audience may help your to choose the right content to deliver, which means you should report what them need or they want rather than what you know. However, you need to find a nice balance between images and words. Another thing we should pay attention to is that we should rehearse many times before the presentation day.

Make Friends

Make Friends 图片发自简书App Am I an outgoing girl? If you say yes, but I am very afraid to have a sudden silence when we talk about. I don't know how to break the silence if he/she said nothing. If you say no, but I can know someone very quickly.

LintCode平台的读者可以阅读笔者文章(在线编程平台推荐-LeetCode)。问题的英文版本描述如下: Continuous Subarray Sum Given an integer array, find a continuous subarray where the sum of numbers is the biggest. Your code should return the index of the first number and the index of the last number. (If their are duplicate answer, return anyone) Example Give[-3, 1, 3, -3, 4], return [1,4].

257. Binary Tree Paths

Binary Tree Paths Given a binary tree, return all root-to-leaf paths. A string concatenation is just too costly. When using StringBuilder, We can just keep track of the length of the StringBuilder before we append anything to it before recursion and afterwards set the length back. Another trick is when to append the "- ", since we don't need the last arrow at the end of the string, we only append it before recurse to the next level of the tree. Hope the solution helps!

iOS delegate、NSNotification效率比较

iOS delegate、NSNotification效率比较 //联系人:石虎QQ: 1224614774昵称:嗡嘛呢叭咪哄 一、delegate的效率肯定比NSNotification高. delegate方法比notification更加直接,最典型的特征是,delegate方法往往需要关注返回值,也就是delegate方法的结果。 比如-windowShouldClose:需要关心返回的是yes还是no。所以delegate方法往往包含should这个很传神的词。也就是好比你做我的delegate,我会问你我想关闭窗口你愿

Leetcode 65. Valid Number

Leetcode 65. Valid Number Validate if a given string is numeric. Some examples: "0" = true " 0.1 " = true "abc" = false "1 a" = false "2e10" = true Note: It is intended for the problem statement to be ambiguous. You should gather all requirements up front before implementing one. 这道题题意很简单,判断一个字符串是否是一个合法的数字表示。但是坑非常多,因为题目没有说明合法的条件范围,比如. } else if (s.charAt(i) == 'e') { if (eSeen || !

leetcode 350. Intersection of Two Arrays II

leetcode 350. Note:Each element in the result should appear as many times as it shows in both arrays.The result can be in any order.Follow up:What if the given array is already sorted? Which algorithm is better? Hash table solution Time: O(m + n) Space: O(m + n) class Solution { public: vector intersect(vector nums1, vector nums2) { unordered_map dict; vector res; for(int i = 0; i = 0) res.push_back(nums2[i]); return res; } }; 采用unordered_map查询效率高, 无序.
