//Part1:

// create a data model to represent your classmates
// 	-think of different attributes of your classmates? what do all of them have ?
// 	-create a factory function.
// 	-create an array to hold the classmates that you created and what you created to it .  
// 	-write a function called displayFriend that takes a mate as an argument and returns the important information in a readable way.
// 	-write a function called addFriend that takes a mate as an argument and add it to you classMates arraya.
// 	-calculate the number of male friends that your class have by writing a function called nbOfMale.

//Part2:
// Using recursion Write a JavaScript function to find the greatest common divisor (gcd) of two positive numbers.
// Write a function called sum that accepts two numbers as parameters, and sum them together but without suming them togther directly
//you can only add one at each summation, you'll need to use recursion in this.
