In each department, the student-to-faculty ratio can be obtained by dividing the number of students by the number of faculty. Write a method that, given:

• an array students containing the numbers of students in different departments,
• an array faculty containing the number of faculty in different departments, and
• the index i of the current department,
returns the student-to-faculty ratio of this department. For example, if the index is i = 2, the number of students in the corresponding department is students[2] = 200 and the number of faculty at this department is faculty[2] = 10, your method should return 20. Use try-catch to catch both possible exceptions:
• an exception arising when the index i is too large, larger than (or equal to) the number of departments; and
• an exception arising when we try to divide by 0.
Return −1 if the first exception occurs and −2 if the second exception occurs.
