TinyURL is a URL shortening service where you enter a URL such ashttps://leetcode.com/problems/design-tinyurland it returns a short URL such ashttp://tinyurl.com/4e9iAk. Requirements: For instance, “http://tinyurl.com/4e9iAk” is the tiny url for the page “https://leetcode.com/...
碰见系统设计题,多想想函数式编程、面向对象编程、设计模式等等,说不定用得上。 // Solution 1: This is a system design problem, not an algorithmic one. Apparently you don't solve a system design problem within 50 lines of code. So get to it. Whenever dealing with system design problems, try...
系统设计的关键,通常是代码复用、接口扩展以及计算并行化。 // Solution 1: This is not an algorithmic, but a system design problem. The problem itself is no challenge, but the follow-up section down below. The key criteria of system design problems are usually code reusability, interface scalabili...
we needs to implement next() and hasNext() method but unlike other problems, we have a new type of data in this problem: NestedInteger. this class is implemented already and provided with nestedinteger interface: IsInteger() getInteger() and getList(). so you have to stay clearly. this is ...
