WalkthroughA new Ruby file introduces two methods: one that assigns and overwrites a local variable, checks if an input is exactly true, and prints a message; another that prints eleven sequentially numbered lines. No additional logic or error handling is present. Changes

Impact AnalysisIntroduction of new methods: doStuff and long_method📢 Medium 🔗 Impacts API A new Ruby file introduces two methods, doStuff and long_method, which are now available for use. Users of this codebase can now call these methods to print specific output based on input or to print a sequence of lines, respectively. Test calling both methods directly to verify their output matches expectations. Check edge cases for doStuff, such as passing values other than true, and ensure long_method prints all intended lines. 🔍 Related Files

Remove useless variable assignments.
The variablefoo is assigned twice but never used. Both assignments are unnecessary and flagged by RuboCop.
- foo = 1- foo = 2 # useless reassignment

🛠️ Refactor suggestion
Simplify boolean comparison and use single quotes.
The comparisoninput == true is not idiomatic Ruby - useinput directly. Also, use single quotes for strings without interpolation.
- if input == true- puts "value is true" # double quotes used unnecessarily+ if input+ puts 'value is true'

In test_file.rb around lines 5 to 6, simplify the boolean comparison byreplacing `input == true` with just `input`. Also, change the string from doublequotes to single quotes since it does not require interpolation, updating `puts"value is true"` to use single quotes instead.| @@ -0,0 +1,23 @@ | |||

🛠️ Refactor suggestion
Use snake_case for method names.
Ruby convention uses snake_case for method names, not camelCase.

In test_file.rb at line 1, the method name doStuff uses camelCase which isagainst Ruby conventions. Rename the method to use snake_case, for example,change doStuff to do_stuff to follow Ruby's standard naming style.| def long_method | ||

🛠️ Refactor suggestion
Refactor repetitive code using a loop.
The method contains repetitive puts statements that violate the DRY principle. This can be refactored to use a loop for better maintainability.

In test_file.rb around lines 10 to 22, the method contains repetitive putsstatements that print sequential lines. Refactor this by replacing the multipleputs calls with a loop that iterates from 1 to 11 and prints each linedynamically. This will reduce code repetition and improve maintainability.
