Create a function finalGrade, which calculates the final grade of a student depending on two parameters: a grade for the exam and a number of completed projects.

This function should take two arguments:
exam - grade for exam (from 0 to 100);
projects - number of completed projects (from 0 and above);

This function should return a number (final grade).
There are four types of final grades:
- 100, if a grade for the exam is more than 90 or if a number of completed projects more than 10.
- 90, if a grade for the exam is more than 75 and if a number of completed projects is minimum 5.
- 75, if a grade for the exam is more than 50 and if a number of completed projects is minimum 2.
- 0, in other cases

Examples:

~~~if-not:nasm
```python
final_grade(100, 12)  # 100
final_grade(99, 0)    # 100
final_grade(10, 15)   # 100
final_grade(85, 5)    # 90
final_grade(55, 3)    # 75
final_grade(55, 0)    # 0
final_grade(20, 2)    # 0
```
