Debugging a Ruby program can be done in a variety of ways. Here is an example of how to debug a Ruby program using the built-in Ruby debugger:
1. Start the debugger by running the program with the -r option:
$ ruby -r debug your_program.rb
2. Set a breakpoint at the line of code you want to debug:
(rdb:1) break
3. Run the program:
(rdb:1) continue
4. Execute the commands you want to test:
(rdb:1)
5. Step through the program and inspect variables:
(rdb:1) step
(rdb:1) list
(rdb:1) info variables
6. When you are done debugging, quit the debugger:
(rdb:1) quit
