The final grade for this course is determined based on two homework assignments with the weight of 10% each, and two exams with the weight of 40% each. You need to write a Node.js program to implement the calculation of your final letter grade based on the rubric of A(93 or higher), A-(90-92), B+(87-89), B(83-86), B-(80-82), C+, C, C-, D+, D, D-, and F(0-59). You need to compute the grade to the first digit after the decimal point, i.e., 90.5, or 89.4. Then, the numeric grade will be rounded up if it is at the border. For example, 89.5 becomes 90.

1. Write a Node.js program to implement the Grade Conversion Problem. You need to specify a set of numbers as an object with four values for each element in the array. 2. Describe the boundaries in this problem. 3. Present one example to demonstrate the normal values of this problem. 4. Present one example to illustrate the abnormalvalues. 5. Present one example to illustrate the concept of equivalent classes.
