In this lesson, we'll grab arrays of values from other arrays, resulting in a nested array. From there, we'll look at multiple ways to flatten the array structure using composition with map and unnest and then refactoring to use chain, AKA flatMap. F…

在Tomcat的server.xml中配置两个context,出现其中一个不能正常启动,交换配置顺序,另一个又不能正常启动,即始终只有第二个配置能启动的情况.如果单独部署,都没有问题.报错大致内容如下: appears to have started a thread named [com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread-#0] but has failed to stop it. This is very lik…
Problem: given an array that contains duplicates (except one value), find the one value that does not have a duplicate in that array. Explain the complexity of your algorithm. So in the array: A = [2, 3, 4, 5, 2, 3, 4] your algorithm should return 5…
In this lesson we'll use a handful of Ramda's utility functions to take a queryString full of name/value pairs and covert it into a JavaScript object so we can access those properties in a more useful way. Along the way, we'll build up a composition…

Given an array of integers A, a move consists of choosing any A[i], and incrementing it by 1. Return the least number of moves to make every value in A unique. Example 1: Input: [1,2,2] Output: 1 Explanation: After 1 move, the array could be [1, 2, 3…

In this lesson, we'll use Promise.all to get an array that contains the resolved values from multiple promises. Then we'll see how we can use Ramda to convert that array of values into a single object using zip with fromPairs. Then we'll refactor to…
Find the unique elements of an array. Returns the sorted unique elements of an array. There are three optional outputs in addition to the unique elements: the indices of the input array that give the unique values, the indices of the unique array tha…

Introduction Log files are files that contain messages about the system, including the kernel, services, and applications running on it. There are different log files for different information. For example, there is a default system log file, a log f…
Scala's object-oriented collections support mutable and immutable type hierarchies. Also support functional higher-order operations such as map, filter, and reduce that let you use expression-oriented programming in collections. Higher-order operatio…
