Observable.merge allows you take two different source streams and use either one of them to make changes to the same state of your data. This lesson shows how you can use a stream of clicks and an interval stream and use either one to update the cloc…

While Angular 2 usually uses event handlers to manage events and RxJS typically uses Observable.fromEvent, a good practice when using Angular 2 and RxJS combined is to use Subjects and push the value through each event so that you can use it as part…

Given a collection of intervals, find the minimum number of intervals you need to remove to make the rest of the intervals non-overlapping. Note: You may assume the interval's end point is always bigger than its start point. Intervals like [1,2] and…

Given a collection of intervals, merge all overlapping intervals. For example,Given [1,3],[2,6],[8,10],[15,18],return [1,6],[8,10],[15,18]. 思路:开始想用线段树,后来想想这个不是动态变化的没必要. 按区间的第一个值从小到大排序,然后跳过后面被覆盖的区间来找. sort折腾了好久,开始搞不定只好自己写了一个归并排序.现在代码里的sort是可用的. class…

Merge Intervals Given a collection of intervals, merge all overlapping intervals. For example,Given [1,3],[2,6],[8,10],[15,18],return [1,6],[8,10],[15,18]. 记返回数组为ret. 先对start排序. 然后对每两个interval(记为a,b),判断是否需要合并. 如果不需要合并(没有交集),则把a装入ret,将b继续往后. 如果需要合并(有交…

Action Bar是在窗口上指示用户位置的组件,同时给用户提供导航和操作.使用Action Bar可以让你的应用在不同配置的屏幕上看起来比较一致.在开始之前,先了解一些相关的术语: Action Bar有以下几项关键功能: 1)为你的App提供一个装饰处,同时也可以让用户知道自己的所在位置: 2)让一些重要的操作以一种可预见的方式变得突出并且可访问(比如搜索): 3)支持风格一致的导航和视图切换手段: ActionBar的API首先在Android3.0(API 11)中被加入,但是可以使用S…
