Now, let’s take a look at a couple of sample assignments that demonstrate our capability and commitment to academic excellence.

Sample Assignment 1: Implementing a Thread-Safe Bounded Buffer in Java

Question:

Design and implement a thread-safe bounded buffer (also known as a circular queue) in Java. The buffer should support multiple producers and consumers using semaphores. Ensure that producers wait when the buffer is full, and consumers wait when it's empty.

Solution (Provided by Our Java Expert):

import java.util.concurrent.Semaphore;

public class BoundedBufferT {
private final T[] buffer;
private int putIndex = 0, getIndex = 0;
private final Semaphore mutex = new Semaphore(1);
private final Semaphore empty;
private final Semaphore full;

public BoundedBuffer(int size) {
buffer = (T[]) new Object[size];
empty = new Semaphore(size);
full = new Semaphore(0);
}

public void put(T item) throws InterruptedException {
empty.acquire(); // Wait for space
mutex.acquire(); // Enter critical section
buffer[putIndex] = item;
putIndex = (putIndex + 1) % buffer.length;
mutex.release(); // Leave critical section
full.release(); // Signal that item is available
}

public T get() throws InterruptedException {
full.acquire(); // Wait for item
mutex.acquire(); // Enter critical section
T item = buffer[getIndex];
getIndex = (getIndex + 1) % buffer.length;
mutex.release(); // Leave critical section
empty.release(); // Signal that space is available
return item;
}
}

Explanation:

This solution uses three semaphores: one to ensure mutual exclusion (mutex), one to track empty slots, and one for filled slots. It ensures proper synchronization between producer and consumer threads.

Our clients received full marks for this assignment and praised the clarity and robustness of the implementation. That’s the power of our programming assignment help USA service—delivering flawless, real-world solutions.

Sample Assignment 2: Build a Mini Compiler in Python for a Subset of Pascal

Question:

Develop a mini compiler in Python that performs lexical analysis and parsing for a subset of Pascal. Your compiler should read input from a .pas file and produce an abstract syntax tree (AST). Support variable declarations, simple arithmetic operations, and if-else conditions.

Solution (Provided by Our Python Expert):

import re

# Token specification
token_spec = [
('NUMBER', r'\d+'),
('ID', r'[A-Za-z_]\w*'),
('ASSIGN', r':='),
('OP', r'[+\-*/]'),
('SEMI', r';'),
('LPAREN', r'\('),
('RPAREN', r'\)'),
('IF', r'if'),
('THEN', r'then'),
('ELSE', r'else'),
('SKIP', r'[ \t]+'),
('MISMATCH', r'.')
]

token_re = '|'.join('(?P%s%s)' % pair for pair in token_spec)

def tokenize(code):
for match in re.finditer(token_re, code):
kind = match.lastgroup
value = match.group()
if kind == 'SKIP':
continue
elif kind == 'MISMATCH':
raise SyntaxError(f'Unexpected token: {value}')
else:
yield (kind, value)

# Example usage
code = "if x := 10 then y := x + 1 else y := 0;"
tokens = list(tokenize(code))
print(tokens)

Explanation:

This lexer breaks down Pascal code into tokens using regular expressions. It's the first step toward building a parser that creates an AST. It’s simple yet effective for compiler design classes.

One of our clients used this as a base to expand into a full-fledged project and secured an A+. That's the caliber of service we aim to provide through our programming assignment help USA offering.
