Question: the shortest path for recycling all garbage Train of Thought: First BFS processes the distance between two spam, and then DFS memory-based search Dp [I] [state] indicates that the status after I is processed is the shortest path of state.

A super disgusting question... An error was found for an hour .... 1. Use C ++ and G ++ to access wa. 2. Check the boundary. 3. Pay attention to the marked decentralization mode. #include #include #include #include

  There is an orchard with many trees and many fruits on it. Otherwise, the ripe fruit must be collected within two days. Given the number of trees in the orchard and the number of fruits on the tree, the upper limit that workers can collect each

To query the maximum value of a certain range of a series, data is updated. Such a question can use a tree array, but it is better to use a line segment tree because interval operations are involved. However, it is also possible to use a tree array,

By default, Oracle databases display dates in DD-MON-YY, where DD is the day, MON is the first three letters of the month (uppercase), and YY is the last two digits of the year. The database actually stores four digits for the year, but only the

We all know that when two pointers direct to the same variable, if one pointer is released, the other will have a problem. To illustrate the problem, I made a very disgusting small example to copy the Code class C {public: C (int v) {ptrInt = new

Notes for a single mode: 1) To design a single pattern, we first need to privatize the constructor so as not to allow external access, so the outside can only obtain a new class through the provided functions. (2) In the single mode of C ++,

Const is the abbreviation of constant. It is not easy to change. In C ++, const is used to modify built-in type variables, custom objects, member functions, return values, and function parameters. 1. const modifies Common variables. 1 const int a = 7

Mode definition: The modifier mode dynamically attaches the responsibility to the object. To expand the functionality, the decorator provides an alternative solution that is more flexible than inheritance. The decorator and the decorator have the
