Stack Overflow gets copy-pastes like this:
Many of these questions are copy pasted from Google Classroom or some similar source. For example, the question below says
A university is receiving applications from students to register for language courses offered in six different languages. Each language has limited seats and time of submission of request is to be used for making a decision. The following are the fields provided in the application: Register Number, Name, Time and date of submission, Preference of language {Option1, Option2, Option3} Devise a solution that would automate the process of allocating the languages based on the order of preference given by students. Use appropriate data structures to process the data. Include provision for swapping of the language that has been allocated for a student on mutual consent.
That's zero research effort. Probably copied from somewhere. [1]
To have quality questions, can we block questions that are mostly pasted?
