Step by step
Solved in 4 steps
- Consider the following function: void fun_with_recursion(int x) { printf("%i\n", x); fun_with_recursion(x + 1); } What will happen when this function is called by passing it the value 0?4. Remove the left recursion from the following production rule to obtain a new rule: A = A '0' | '1' | A '2' | '3' | A '4' | '5'Write The code for a basic recursive quicksort member function.
- True/False 5. All proper recursive definitions must have exactly one non-recursive base case.What happens if a recursive function does not handle base cases correctly?Recursive Syntax The recursive structure i.e of natural language like English can be expressed in syntax rules written in the format known as BNF (Bachus-Naur Form). While BNF is ordinarily used as a guide for parsing (that is, determining whether and how a given string follows the syntax rules), An example of this can be found in the sample program SimpleRandomSentences. You should write a similar program that implements the following rules:<sentence> ::= <simple_sentence> [ <conjunction> <sentence> ]<simple_sentence> ::= <noun_phrase> <verb_phrase><noun_phrase> ::= <proper_noun> |<determiner> [ <adjective> ]. <common_noun> [ who <verb_phrase> ]<verb_phrase> ::= <intransitive_verb> |<transitive_verb> <noun_phrase> |is <adjective> |believes that <simple_sentence><conjunction> ::= and | or | but | because<proper_noun> ::= Fred | Jane | Richard Nixon | Miss…

Your Answer: 1 # Put your answer here 2 SubmitRecursive Parsing Calculator HINT: Before attempting this exercise, see the simplerecursiveparser.java in the example programs of the recursion unit on QM+ and the related booklet about Language, grammars and recursion that explains it. Write a program that recursively parses expressions, input as strings, from the following recursively defined language and calculates and prints out the answer to the calculations. Legal expressions in this language involve putting the operator before its arguments (this is called Polish notation). = * | T = 0|1|2|3|4|5|6|7|8|9|A|B|C Instead of writing 3*2, in this language you write *32 (which evaluates to 6). EXP stands for expressions. means multiply the two digits that follow (after evaluation) so *24 is 8 and *5*34 is 60 as it first multiples 3 and 4 to get answer 12 then multiplies 5 and 12 to get 60. Tn means add the next 3 numbers from n (so eg T3 means 3+4+5=12, T7 means 7+8+9-24), DIGIT gives a way to express numbers up to 12 as a sıngle…
