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

The first time the scan element will be character statistics, the second pass through to find the first count of 1 characters.Task 4: All subsets of a stringRef

, intersection, and difference operations. So, if you want to perform some normal collection operations on the keys of the collection, you can use the key view objects directly without first converting them to a set.The dictionary's items () method returns an element view object that contains (key, value) pairs. This object also supports collection operations and can be used to find out which two dictionaries have the same key-value pairs.Although the values () method of the dictionary is simila

"Merge Sort" Here we use recursive algorithm to keep the list in two, base case is no element in the list or only one element, because this sub-list is bound to be a positive sequence, and then gradually merge the two sorted sub-list into a new positive sequence table, until all the elements sorted."This is a process from the bottom up (bottom-up)Divides the list from the middle into two sub-lists until it reaches the bottom, with only one element in the sub-list　　Then, the two sub-lists are mer

However, the data structure described here can only be described as the logical structure of the data, that is, it is only abstract in our mind, but in the specific storage also need to use this logical structure to express the reality. Since most of our computer functions are re

First, insert sortWhat is insert sort: insert sort is to insert a value into an ordered data by size, and after inserting the value, the data is still in order.Time complexity for inserting sorting: The large O method is O (n^2).
