Note: All programs are written in Java 18.0.1 and tested on JDK 18.0.1 Note: In cycles 1, 2, & 5 internal lab exams were conducted and are separetely uploaded in the repository

1. Clone the repository
2. go to the directory of the program you want to run
3. Open the terminal in that directory
4. Type javac <filename>.java to compile the program
5. Then type java <filename> to run the program
6. If you want to run the program with input, type java <filename> < input.txt in the terminal
7. If you want to run the program with output, type java <filename> > output.txt in the terminal
