Hello, I have an array of hash and hash of hashes that I want to compare

Array:

completed_courses = [ 
                       {
                         'type' => 'core',
                         'name' => 'Discrete Structures',
                         'title' => 'CS 130'
                       },
                       {
                         'type' => 'core',
                         'name' => 'Intro to Computer Science',
                         'title' => 'CS 140'
                       },
                        {
                         'type' => 'core',
                         'name' => 'C++ Programming',
                         'title' => 'CS 256'
                       }
                  ];

I want to compare and remove the entry from schedule if the title in completed courses is same to Course in schedule. So after comparing the schedule should look like this. 
schedule = {
           'CS 241 Section 02' => {
                                        'Course' => 'CS 241',
                                        'Time' => '8:00 AM - 9:00 AM',
                                        'Class number => 35465,
                                        'Room' => 8 302'
                                  },

           }

Any ideas on how to achieve that would be appreciated thank you.
