+ belong to higher precedence than - both left associative x - y - w + u + v Draw abstract syntax tree

Please help me with this Principles of Programming Languages homework. The question is attached along with Example 4.7. Thanks!

I need help Designing a Java compiler for a Simple Programming Language involves creating a software system that can translate code written in the Simple Programming Language (SPL) into machine code that can be executed on a computer. The compiler needs the follow  Defining the syntax of the SPL, including its basic data types, control structures, and functions. Implementing a lexical analyzer to tokenize the SPL source code into a stream of tokens. Implementing a parser to construct an abstract syntax tree (AST) from the token stream that represents the structure of the program. Implementing a semantic analyzer to check for type errors, undefined variables, and other semantic errors in the program. Generating intermediate code from the AST, such as three-address code or bytecode. Optimizing the intermediate code to improve the efficiency of the generated machine code. Generating the final machine code, such as x86 assembly language, that can be executed on a computer. I…

I need help developing a parser that can take a sentence generated by the context-free grammar and parse it into a parse tree, which can be used to represent the structure of the sentence. Like the example given

Let L2 be the language defined as follows: L2 ={ 0"1mO" | n, m 20} Which of the following context-free grammars generates the language L2? (Here all uppercase letters are variables) A- OA0 | B B - 1B |E O S-S|A A→A|B|E B →S O A-OAO | 1A| E S- OsO |A A-1|S|E

The second image contains what 7.1.2 was asking for the topic is automata theory

I keep getting the wrong answer can you please help me with this: Could you assist me with question 2.7 part C? I'm having difficulty with this problem and would greatly appreciate help in creating a state diagram for the push-down automaton in part C. question for 2.7 2.7 Give informal English descriptions of PDAs for the language. c. {w#x | w R is a substring of x for w, x ∈ {0,1} ∗ }

Consider the following Grammar:A-> ABd|Aa|aB-> Be|bRemove left recursion.

(1) Fill the blanks to complete the following sentences that describe the relations between regular expression, regular language, and regular gramma. You can also use your own statements to describe the relations. there is an NFA machine to (i) A language L is regular (ii) A language L is regular (ii1)A language L is regular it. there is a regular expression r to it. there is a regular grammar G to it.

I added my incorrect answer and i think I am very close.I'm consistently arriving at an incorrect answer. Would you mind aiding me with question 2.7, specifically part C? I'm encountering challenges with this particular problem and would sincerely appreciate assistance in developing a state diagram for the push-down automaton in part C.question for 2.7 2.7 Give informal English descriptions of PDAs for the language. c. {w#x | w R is a substring of x for w, x ∈ {0,1} ∗ }
