Explanation: generate a question paper of 100 marks total of which 20% (ie, 20 marks) 
worth of questions should have the Difficulty = Easy, 50% having  Difficulty = Medium
and 30% having Difficulty = Hard

Edge Cases

1. if totalMarks field is missing then throw error "Total marks field is required"
2. Sum of percentage of all the difficulty must be equal to 100%
3. if number of question of a particular difficulty exist in data is smaller than
   the number of question of that difficulty required in question paper then throw
   error " No. question of difficulty : {Difficulty} is lesser then required number "
   Example :
     required No. of question of difficulty Hard : 30
     No. of question in data of difficulty Hard : 25

     error thrown : " No. question of difficulty : Hard is lesser then required number "
