'''
We need a function that can transform a number into a string.
What ways of achieving this do you know?

Examples:
number_to_string(123) /* returns '123' */
number_to_string(999) /* returns '999' */

# 2nd try - after refactor
def number_to_string(num):
    # Return a string of the number here!
    num=str(num)
    return num

# 1st try
def number_to_string(num):
    # Return a string of the number here!
    num=str(num)
    return(num)
