Currency converter

Working prototype, needs tests

data.py

def reverse_string(s): return s[::-1]

print(reverse_string("hello"))

solver.py

def hello():
    print("Hello, World!")

helper.py

def memoize(fn):
    cache = {}
    def wrapper(*args):
        if args not in cache:
            cache[args] = fn(*args)
        return cache[args]
    return wrapper

@memoize
def expensive(n):
    return sum(range(n))

print(expensive(1000000))
