🧠 VJTI CoE Internship – Reverse Engineering Challenges

This repository contains three reverse engineering tasks I solved as part of my internship at the Centre of Excellence (CoE), VJTI Mumbai. Each Windows-based executable required analysis to determine the correct input string that would cause the program to output "Correct".
