In previous posts, the depth-first traversal of graphs was introduced, and recursive and non-recursive implementations were carried out respectively. BFS cannot be implemented recursively, and the most widespread implementation is the use of queues.

1. The purpose of the default parameter C + + can define default parameter values for functions. Typically, when a function is called, the corresponding argument is given for each parameter of the function. For example:void delay (int loops);
