| 2 | +Dr. Max has conducted the academic task in his class with 5 Multiple Choice Questions each having 4 options A/B/C/D. He wanted to write a program which can evaluate the test papers of all the N students such that each correct answer is awarded 1 mark and for incorrect answer penalty is 0.25 marks. |
| 3 | + |
| 4 | +The program must read the number of students N and the the answers of all the N students in the form of a String. If any question is not attempted by any student, then X should be given as input corresponding to that question e.g. ABAXD |
| 5 | + |
| 6 | +It is expected that the marks of all the N students are displayed separated by SPACE. |
| 7 | + |
| 8 | +Input Format |
| 9 | + |
| 10 | +First Line of the input reads the String of CORRECT ANSWERS |
| 11 | + |
| 12 | +Second Line of the input reads the number of students N |
| 13 | + |
| 14 | +Next N lines read the answer Strings of the N students respectively. |
| 15 | + |
| 16 | +Constraints |
| 17 | + |
| 18 | +N > 0 |
| 19 | + |
| 20 | +Input characters can be either in Upper Case or Lower Case |
| 21 | + |
| 22 | +Output Format |
| 23 | + |
| 24 | +Print the marks of all the N students separated by SPACE |
