C++ does not allow to return an entire array as an argument to a function. However, you can return a pointer to an array by specifying the array's name without an index. If you want to return a single-dimension array from a function, you would have t…

Higher order Array functions such as filter, map and reduce are great for functional programming, but they can incur performance problems. var ary = [1,2,3,4,5,6]; var res = ary.filter(function(x, i, arr){ console.log("filter: " + x); console.lo…

In C++03, the return type of a function template cannot be generalized if the return type relies on those of the template arguments. Here is an example, mul(T a, T b) is a function template that calculates the product of a and b. Arguments a and b ar…

Merge sort is a recursive sorting algorithm. If you don't understand recursion, I recommend finding a resource to learn it. In brief, recursion is the act of a function calling itself. Thus, merge sort is accomplished by the algorithm calling itself…

Convert from list Apply np.array() method to convert a list to a numpy array: import numpy as np mylist = [1, 2, 3] x = np.array(mylist) x Output: array([1, 2, 3]) Or just pass in a list directly: y = np.array([4, 5, 6]) y Output: array([4, 5, 6]) Pa…

In JavaScript, functions are first-class objects; that is, functions are of the type Object and they can be used in a first-class manner like any other object (String, Array, Number, etc.) since they are in fact objects themselves. They can be “store…

One aspect of control flow based type analysis is that the TypeScript compiler narrows the type of a variable within a type guard. This lesson explores how you can define functions and type predicates to create your own type guards similar to the Arr…

Array.from方法可以把一个类数组或者课遍历对象转换为一个正真的数组 语法 Array.from(arrayLike[, mapFn[, thisArg]]) 参数 arrayLike 想要转换成真实数组的类数组对象或可遍历对象. mapFn 可选参数,如果指定了该参数,则最后生成的数组会经过该函数的加工处理后再返回. thisArg 可选参数,执行 mapFn 函数时 this 的值. 举个栗子: 把类数组对象转化为数组 (function(){ var arr = Array.from…

Array.form的用法 1.可以将各种值转为真正的数组,并且还提供map功能.这实际上意味着,只要有一个原始的数据结构,你就可以先对它的值进行处理,然后转成规范的数组结构,进而就可以使用数量众多的数组方法. 2.另一个应用是,将字符串转为数组,然后返回字符串的长度.因为它能正确处理各种Unicode字符,可以避免JavaScript将大于\uFFFF的Unicode字符,算作两个字符的bug. <!DOCTYPE html> <html> <head> </h…

17.6 Given an array of integers, write a method to find indices m and n such that if you sorted elements m through n, the entire array would be sorted. Minimize n - m (that is, find the smallest such sequence). 为了更好的理解题意,我们通过一个例子来分析,比如我们有如下的数组: 1, 2,…

首先,slice有两个用法,一个是String.slice,一个是Array.slice,第一个返回的是字符串,第二个返回的是数组 在这里我们看第二个方法 1.在JS里Array是一个类 slice是此类里的一个方法   那么使用此方法应该Array.prototype.slice这么去用   slice从字面上的意思很容易理解就是截取(当然你不是英肓的话)   这方法如何使用呢?   arrayObj.slice(start, [end]) 很显然是截取数组的一部分 2.我们再看call  …
