/* /*The method draws on the hdoj Forum and has not dealt with any questions that can be taken back. Therefore, it is very tricky to deal,The memory burst for the first time. For the output is-1, I initially considered a problem, but I don't know how to solve it.Later, I came to the Forum and thought it was because of the endless loop caused by my code.The deformation of BFS really makes people feel a little bit ..*/# Include # Include # Include # In

Dot here ^_^ Title description in the ancient Warcraft legend, there are two legions, one called the Scourge, one called Janissary. In their area, there are n passes, numbered 1.

walk on it.1:the area contains nothing, Ignatius can walk on it.2:ignatius ' start position, Ignatius starts his escape from this position.3:the exit of the Labyrinth, Ignatius ' target position.4:the area contains a bomb-reset-equipment, Ignatius can delay the exploding time by walking to these areas.Outputfor Each test case, if Ignatius can get out of the labyrinth, you should output the minimum time he needs, else you should just output-1.Sample InputSample Output4-113I do not want to explai

Breadth-first traversal algorithm (BFS) and breadth-bfs Top 10 algorithms: This article describes how to implement the Java-based graph breadth-first Traversal Algorithm in the form of examples. The specific method is as follows: How to store a graph using an adjacent matrix: 1. determine the number of vertices and edges of the graph.2. The input vertex information is stored in a one-dimensional array

670 SourcePKU The question is to give you two four-digit numbers, A and B. Then, each time a can change the number of A's digits in ten or ten digits, and find the minimum number of times that B needs, of course, each time you change the number, the number must be a prime number, if you cannot convert A to B under the condition that each transformation is a prime number, output impossible; otherwise, obtain the minimum number of times, therefore, the simple idea of this question is to search fo

the same solution so the search method is also different, the problem requires a number of state solutions, and this requires a special state solution, which can be seen in two ways to apply the problem. To solve the problem only two, the state of the use of BFS, no brain that problem solved, and the second problem for starting from 1 o'clock in the morning, to 6 o'clock in the afternoon has been to do with BFS
