Define denotational semantics for the language of octal (base 8) numerals. Use the definition to find the value of “752”. You must define M_dec as a semantic function that maps syntactic objects written as octal numbers (with no decimal points, i.e., no fractions) to a set of non-negative decimal integer values. For Example, given the octal string “752” then: M_dec(“752”) would return 490 as its equivalent decimal value.

3. Given the following BNF grammar: -> d c | cd -> a la -> b | b Use the top-down recursive descent method which we discussed in the class to implement a parser (i.e. tdrd.parser.py) in python3 for the above BNF grammar. The input data file name is given from the command line. You may assume that there is a space character between two terminals (e.g. a a adc b ) in the data file.
7. a. Write a BNF grammar for identifiers that consist of an arbitrarily long string of letters and digits, the first one of which must be a letter. b. Using your grammar from Exercise 7a, show a parse tree for the identifier AB5C8.
