Strings
Python programmers write variable names in snake_case, where each word is lowercased and joined by underscores. JavaScript programmers write variable names in camelCase, where the initial word is lowercase, and other words are capitalized and jammed together.
Given a variable name in snake_case, return a string with that variable name written in camelCase.
For example:
>>> snake_to_camel("hi_balloonicorn")
'hiBalloonicorn'
We’ve given you case.py, which includes the stub of a snake_to_camel function:
def snake_to_camel(variable_name):
"""Given a variable name in snake_case, return camelCase of name."""
