Link: codeforces 459e pashmak and Graph Given a directed graph, each edge has its weight. You must select a route to ensure that the edge weight is strictly incrementing and the longest path is output. Solution: sort the edges by weight, add the

Use the following code to import a specified namespace. Not only is the namespace imported, but a prefix local is also specified for the namespace. You can also specify it as another prefix name, which can be customized. After the import, the public

Why use block variables? Because when our programs are complicated, we need to call a function in a function and define it outside, which is inconvenient to implement, however, with block variables, we can define a block variable within a function,
