Using class rec as a node, there are types var, fun, arr, etc., and actions usfun, usassign, etc
Create initial node in lex
In Bison, define first, obtain a global map, link the desired elements on the nodes of all action types and then judge the action type of each node

When DFS traverse the tree, the node of the action type is assigned a value of the corresponding type, which is convenient for use in nested calls later
In the recs of rec, for the array will store the value related to its size, the number of values represents the number of dimensions, for Exp expression we will store the result of the operation in the val property of rec, for return will look for a specific statement, get its val
