# Project 1 Question 3 part a code - Python

# (5 points) Arrays of Integers
# (a) (2 points) (You must submit code for this question!) Implement a function getRandomArray(n)
# where the output is an array of size n, and contains distinct random numbers (in
# other words, no two numbers in the array should be the same number). Math.rand()
# might be useful here.
