Hi.. I have two methods.but the parameter will be changing. For the first method i send only one parameter(f). But for the second method i'll send 3 parameters(f,search_string_1,search_string_2). And also for 3rd Method i send Two Parameter(f,search_string).

Is it possible to optimise below methods into Single Methods . How can i combine the below Three Methods into one method pls help me.

#method 1 def check_chat_type(f) Dir.foreach(File.join(RAILS_ROOT + "/public/ACMServer_exe/ChatHistory",f)) do sub_folder_name|    if sub_folder_name.include? "Vs"      get_path(f,sub_folder_name)    end end end

#method 2 def check_chat_type(f,search_string_1,search_string_2)   Dir.foreach(File.join(RAILS_ROOT + "/public/ACMServer_exe/ChatHistory",f)) do   >sub_folder_name|     if sub_folder_name.include? "Vs"       if sub_folder_name.include?(search_string_1)         if sub_folder_name.include?(search_string_2)           get_path(f,sub_folder_name)         end       end     end   end end

#Method 3 def check_chat_type(f,search_string)   Dir.foreach(File.join(RAILS_ROOT + "/public/ACMServer_exe/ChatHistory",f)) do   >sub_folder_name|     if sub_folder_name.include? "Vs"       if sub_folder_name.include?(search_string)         get_path(f,sub_folder_name)       end     end   end end

# this makes param 2 and 3 optional (if none is passed default values are set to empty string): def check_chat_type(f, search_string_1="", search_string_2="") ...
