10-20-30 A simple solitaire card game called 10-20-30 uses a standard deck of the playing cards in which suit is irrelevant. The value of a face card (King, Queen, Jack) is 10. The value of an aces is one. The value of each of

Vector Elements stored continuously Vector C; C. Back () returns the last data and does not check whether the data exists. C. Clear () removes all data from the container. C. Empty () determines whether the container is empty. C. Front () returns

Vector is a continuous memory block, while deque is multiple consecutive memory blocks. list is the storage of all data elements separately. It can be that any two elements are not consecutive. The query performance of vector is the best, and it is

1. Basic operations of Vector (1) add, delete, and obtain dynamic array elements The Code is as follows: # Include # include using namespace STD; // add and delete array elements and obtain int main (void) {vector V1; v1.push _ back (1); v1.push _

The types of sequential containers are: vector,list, dequeSequential container adapters:Stack//Advanced post-stackQueue//FIFO queuesPriority_queue//Priority queue at priority management level1. Header files#include // Each header file

Maps are associative, andvectors,lists,anddeque are sequential in type. Map: Underlying mechanism rb-tree(red-black tree), automatic ordering of elements, key-value pairs. Vector: operates in a similar way to array, with dynamic space growth. is a

STL container details, stl container details STL containers can be divided into the following categories:I. Sequence containers, including vector, list, deque, string. 2. Associated containers: set, multiset, map, mulmap, hash_set, hash_map,

Bidirectional queueTime Limit: 1000 MS Memory limit: 65536 KDescriptionThink about two-way linked list ...... The definition of a two-way queue is similar. That is to say, the end of a queue is also the first. Both ends can be used to join the queue.
