Print N ... 1 1 2) 3 5　　The rewritten fab function can meet the requirements of reusability by returning the List, but more experienced developers will point out that the memory consumed by this function will inc

Java Iterable interface and IteratorJava Iterable interface and Iterator iterator Iterator The interface is defined as follows: public interface Iterator { boolean hasNext(); E next(); void remove();} This interface only contains three functions. The hasNext () and next () methods appear in our common set traversal.Functions:Use next () to obtain the next element in the sequence. Use hasN

1.1 iterable literal meaning: iterative, repeatableiterableIs the new type introduced by the ES6 standard. and Array , Map and Set all belong to the iterable type1.2 Why join a iterable type? Traversing the array can take the subscript loop, and traversing the map and set cannot use the subscript. The collection type is not uniform. For a loop of typ

Total: Java provides a relatively complete set of container classes, the basic types are: List, set, Queue, Map, these object types are called collection classes.one, interface inheritance relationship:Iterable interface, in Java.lang package, Collection, List, Queue, set interface inherit Iterable interfaceAs can be seen, list, Queue, set these three interfaces are in the Java.util package, inherit from the collection interfaceThe map interface does

Off Topic:Recently, because the course needs to get into the Python language. Because Java, C + +, and other strongly typed static languages have been used all the time, it is now suddenly true that Python does feel a great difference.The intuitive feeling is that in Python you can always find something that makes the code smart, concise, efficient, and aesthetically pleasing, making the beginner's process of writing the code full of surprises, and gradually becoming fond of python. And the offi

Refer to official Documentation:1 Iterable is an object that can return its members . Includes sequence types (list,str,tuple) and not-sequence types (dict, file objects), objects and classed defined with an __iter__ ( ) method or a __getitem__ () methodWhen a Iterable object is passed into the ITER () method (also called the __iter__ () method), a iteratoris returned. This is the method of explicitly creat

When you look at a function's description document, it often appears that the parameter of the function is iterable, so what does iterable mean?Iterable: An iterative, iteratorIn Python, iterable is considered an object that can return one of its members at a time (that is, the elements inside the object), so that the

JavaScript learns to record Day4-map, set, and iterable[TOC]The default object representation of JavaScript {} can be thought of as a Map data structure in another language Dictionary , or a set of key-value pairs.But the JavaScript object has a small problem, which is that the key must be a string. But actually number or other data type as a key is also very reasonable.To solve this problem, the latest ES6 specification introduces new data types Map

Java.lang.IterableJava.util.IteratorIterator is an iterator class, and iterable is an interface.Many classes implement the Iterable interface so that the object can call the iterator () method.are generally used in combination, such asThe HashMap class implements the Iterable interface, and when you want to access or print all the contents of a map, you can:1 Has

This function is used to traverse all elements from an iterative object iterable , and evaluates to True When each element is run as a parameter to a function object. element is preserved, while the element that is False is skipped, which is the goal of filtering unwanted elements. The parameter iterable is an iterative object, such as a list, dictionary, string, or function object with an iterator. Para

(Reproduced: http://blog.csdn.net/passionkk/article/details/49929887)In Python list,truple,str,dict these can be iterated, but they are not iterators. Why?Because there is a big difference compared to iterators, list/truple/map/dict the size of the data is deterministic, that is to say how many things are known. But the iterator is not, the iterator does not know how many times to execute, so it can be understood to not know how many elements, each call to next (), will go down a step, is inert.

Parent interface of Collection:iterable interfaceA class that implements the Iterable can is used with the new for-loop.The interface has only one Iterable method:Public interface IterableIt is possible to use your own collection type classes with the new For-loop. To does so, your class must implement the java.lang.Iterable interface. Here is a very basic example:public class MycollectionAnd here is the co
