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 、實現(xiàn)了自動轉換系統(tǒng)的泛型問題中的類型參數(shù)化問題,解決了apla提供泛型機制,而java語言不支持泛型機制的矛盾。
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.
