fundamentals of data structures

operations, using for-in, for, while, and do-while for looping. Wrapping conditions and loop variable parentheses can be omitted, but curly braces on the body of the statement are required.(6.1) for in control flowLet Indivadulscore = [70,66,80,90,56,34]var score = 0For S in Indivadulscore{If s>60{Score + = 20}else{Score + = 100}}Note: Look at the differences in the syntax of the control flow you wrote earlier(6.2)? indicates an optionalvar optionstring:string? = "Hello,world"Optionstring = = N

parameters to determine a list: (or if a function is expected to operate on a linked list.)Should we at least receive the information from the linked list??? ）Only need one parameter: the head pointer, because through it we can launchAll information about the linked list.(the list of programs should be sure to knock it out by themselves)List categories: single-linked listDouble Linked list:Each node has two pointer fieldsCircular link ListCan find all the other nodes through any nodeSingle-link

1. Use LinkedList to simulate the collection of stack data Structures and test:The meaning of the title is:Your own definition a collection class, within which the LinkedList simulation can be used, encapsulated into its own method using the LinkedList function method .2. Code parsing:(1) define own collection class Mystack, simulate stack data structure ( advanc

The algorithm and data structure, from the very beginning, the realization of dynamic array is first seen.Array.h#include Main.cpp#include "Array.h" int main () {Array arr1 (2); Arr1.printarray (); arr1. InsertAt (1, 1); Arr1.printarray (); arr1. Deleteat (1); Array arr2 (ARR1); Arr2.printarray (); arr1. SetAt (1, 1); Array ARR3 = Arr1;arr3.printarray (); Arr3. Pushback (2); cout Output resultsCome on, that's it.Fundamentals of Algorithms and

Simple single-linked list implementation, the data type is defined as an int, if you want to be generic, you need to change to a template class, and then slightly modified to the next.List.h#include Main.cpp#include "List.h" #include Output:There are some features not implemented, such as the insertion of elements in the specified location, linked list search, etc., because there is no iterator, with index do not be too good, simply do not write forge

Switch (Boolean) {///Advantage structure is clear, high efficiency, the disadvantage can only judge the case of equal numbers.Case 1:StatementCase 2:Statement。。。。。。Default:Statement}Two.

Note: This blog is my understanding of the data structure, many local understanding may not be appropriate, but also ask the reader to learn dialecticallyUnderstanding data structures from the macro levelMany times we have been working hard, but don't know why ...After a year of work, re-think of the university's data

JavaScript data structures and algorithms stack and queue, data structures and algorithms Learning cause Once upon a visit to V2EX, I encountered such a post.The mathematics is completely returned to the teacher. I want to learn some basic mathematics, which is probably high school. What books do I recommend?The poster

solving methods and expect to be confident in your ability to deal with problems, and you know the difficulty of learning some programs. The complexity of large-scale problems and the corresponding solutions greatly outweigh the underlying issues associated with the approach. This chapter focuses on two aspects of the content. First, review the frameworks that must be followed in the study of data structures
