The ordered symbol table based on parallel array and two point lookup is the classic search algorithm in the algorithm. This program uses the Python language to realize the ordered symbol table.
ST.py contains two classes, ST and OrderedST.
ST is an unordered symbol table based on a chain table. The key values are inserted in the list in order.
OrderedST is an ordered symbol table based on parallel arrays. The two point lookup algorithm is used when searching.
