Assignment 04 You are given the main class RecursiveMethods.java which invokes methods that can be selected from a menu. Your task is to implement two of these methods. -The first method isPal(s) determines whether a given string s is a palindrome. For example “12321” is a palindrome but “1231” is not. Currently the method isPal […]

Stripe Onsite 重新整理-http json 参考这个json https://drive.google.com/open?id … YqJ4o1uwASwXo0uD_3w 里面有六个request/response。从第一个开始replay，按照顺序到第六个。先replay 然后compare status code。之后你会发现前两个能pass。后四个会fail。 第一个和第二个request的body和url都是固定的。第一个的respone里面会有一个auto generated customer id。第二个respone里面会有auto generated charge id。 你要create一个mapping。把提供的json里的id replace成你得到的id。 最总你要replay六个request 然后每个status code都要match就行。 请问楼主json-replay那道题, 最后把json里面的id替换成得到的id, 是要进行文件写入操作吗? 不是 不用文件写入。你在memory里改一下就行了。 integration出来新题了。之前我把地理的面经翻了一遍都说的是send request那个题。结果当时出了个状况是不知道为什么我git clone不下来他们的库一直提示权限问题，于是考官向发邮件给我，结果Gmail发不了，我说你Google drive把要不。于是他Google drive了下我download下来，此时已经耗费十五分钟以上。。。然后题目有两个问，第一个是用他给的sample代码读file然后parse一个Jason的object，就照着他给的方法写就好了；第二个问是用OKHTTP的库来send request，他给了一个图片的URI，然后去比较response body里面的什么什么（没做完 毕竟前面浪费了十五分钟以上） 第二轮是地里提到过的：给a file of request in JSON format，然后写http client提交这些requests到Stripe的endpoint，再解析返回的JSON response。主要考察对相关语言JSON/RPC lib的熟悉度。followup是response里携带后续request的一些信息，如何handover这些信息给后续reqeusts并提交，没做完。 Request Replay. 通过Gson解析json，通过OkHttp向api.stripe.com发送请求并且比对返回的数值。 第一轮是json replay，follow up是新id到old id的mapping 第一个小时考地里那个根据json文件发requeset，然后validate返回的东西。java建议的库是okhttp和gson，请务必务必熟悉库OTZ，现场查文档真的窒息 第二问我的面试官没直接告诉我要做什么，是跟我说让我自己找为啥api

Stripe Onsite 重新整理-rate limiter 比如 1s 限制 5 个请求, 可以在 1s 的开始就获取全部 5 个请求; 而不是必须等待 200ms 才能获取一个请求. 时间是滑动窗口. 需要自己写测试用例. 写测试用例如何避免 sleep , 比如题目是 1s 限制 5 个请求, 怎么测试能尽快验证超过 1s 的情况 (用 mock, mock 当前系统时间) 第一问： 2秒之内只能发5个request， 怎么limit 第二问： 如果request 里面有customer id, 怎么让这个rate limit是customer specific的 （就是 customer 1 的limit超过了 并不影响 customer 2 的 request） 第三问： 有的request

Instruction Representation Review (1/2) °Logical and Shift Instructions • Operate on bits individually, unlike arithmetic, which operate on entire word. • Use to isolate fields, either by masking or by shifting back and forth. • Use shift left logical, sll,for multiplication by powers of 2 • shift right arithmetic, sra, close but wrong for divide

In-Memory Virtual File System 1 Overview The goal of this project is to develop an in-memory Virtual File System (VFS), named the Comp VFS (CVFS), in Java. A VFS is usually built on top of a host file system to enable uniform access to files located in different host file systems, while the CVFS simulates
