- 5-Write an EBNF rules that describe the following while statement of Java. Then, write the recursive-descent subprogram in Java for the EBNF rule. Please submit your source code and a screenshot of the parsing of the following examples. do { if ( number % 2 == 0 ) even ++; number=number+1; } while (number <= 10)Write an EBNF rule that describes the for-statement of Java or C++. Write the recursive descent subprogram in Java or C++ for this rule.Write a recursive function in C that returns a value of 1 if its string argument is apalindrome and zero otherwise.* Note that for the function parameters, you need to accommodate for the shrinkingstring, so that the string shrinks both from beginning and end after each recursive call.** Think about the simple cases or base cases. The 2 base cases have conditions thatwould return 0 and return 1 independently.For the palindrome, create a driver program. First ask the user to enter anystring through the keyboard. Then remove all the spaces and punctuations from thestring. Also, remove any letter capitalization from the string. Finally, pass the string tothe palindrome function through a function call.
- Using the syntax of C, write a recursive-descent subprogram named initializer that corresponds to the following rules (taken from the C99 standard): initializer: assignment-expression { initializer-list } { initializer-list,} Note that { and } are terminals, not metasymbols. Assume that recursive-descent subprograms named assignment-expression and initializer-list already exist.In your own words, explain the two rules that a proper recursive definitionor function must followWhy is it required to provide a base case for every recursive function?
- QUESTION 1 Write in C++ a descent recursive parser for the following grammer: S-> abSAc| d A-> bAe | fWrite a pseudo code of recursive algorithm that takes a string and checks whether the string is palindrome or not Implement the pseudo code in C++.Recursive 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…
