## Shortest path algorithm

There are two main solutions to the shortest path algorithm: 1. Dijestra algorithm for single source: One point to all points. The main feature is to take the starting point as the center and expand outward layer by layer until it reaches the end point. Dijkstra algorithm is very useful Representative shortest path algorithm Algorithm details: ...

## vector container of C + + high-order STL

The vector container is the best alternative to arrays vector container can also be used to save and manage a large amount of data of the same type, but it is superior to array in terms of memory management and access to data elements: The dynamic increase or decrease of the capacity of the vector container replaces the fixed capacity of the a ...

## STL source code analysis Reading Note 4 (Sequence container list)

1, Overview   list and vector in the previous chapter are the most commonly used containers in our daily development. However, unlike vector, list is not an absolutely fixed container of continuous space. The reason why it is designed in this way is to consider the time consumption of deleting and inserting continuous space. STL list is a ...

## Implementation of hash table

1. Hash table Note 1 Note 2 Hash table (also known as hash table) is a data structure that is accessed directly according to the key value. That is, it accesses records by mapping key values to a location in the table to speed up the search. This mapping function is called hash function, and the array storing records is called hash table. Hash ...
