We denote many typical arithmetics with apla , such as , non - recursive tree traversals , dijkstra , topological sorting etc . the test result indicates the program transformer can improve the program ' s reliability and development efficiency . it can replace softeware blue collar to complete mechanical and creative work 5 、实现了自动转换系统的泛型问题中的类型参数化问题,解决了apla提供泛型机制,而java语言不支持泛型机制的矛盾。
In computer science, tree traversal refers to the process of visiting (examining and/or updating) each node in a tree data structure, exactly once, in a systematic way. Such traversals are classified by the order in which the nodes are visited.
