/*
Description:
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:

finalGrade(100, 12);  // 100
finalGrade(99, 0);    // 100
finalGrade(10, 15);   // 100

finalGrade(85, 5);    // 90

finalGrade(55, 3);    // 75

finalGrade(55, 0);    // 0
finalGrade(20, 2);    // 0
*Use Comparison and Logical Operators.
*/

function finalGrade (exam, projects) {
  if(exam > 90 || projects > 10) return 100;
  if(exam > 75 & projects >= 5) return 90;
  if(exam > 50 & projects >= 2) return 75;
  return 0;
}
