The Java programming language makes multithreading so simple and effective that some programmers say it's actually natural. Although the use of line turndown in Java is much easier in other languages, there are still some concepts that need to be mastered. One important thing to keep in mind is that the main () functio

Each number in the first row represents the mileage between the first city in the list of cities and the other city in turn. The mileage between the same city in the table is 0.Finally, you will read the names of two cities.Output format:Output the distance between the two cities.Input Sample:HagzouHugzoujigxng # # # 01108708 1
