    python

    I didn’t realize it was december until this afternoon. I’ve generally chosen a new or spartan lang to challenge myself, but I’m going easy mode this year with python and just focusing on meeting the requirement.

    solution 
    import aoc

def setup():
    lines = aoc.get_lines(1)
    l = [int(x.split()[0]) for x in lines]
    r = [int(x.split()[1]) for x in lines]
    return (l, r, 0)

def one():
    l, r, acc = setup()
    for p in zip(sorted(l), sorted(r)):
        acc += abs(p[0] - p[1])
    print(acc)

def two():
    l, r, acc = setup()
    for n in l:
        acc += n * r.count(n)
    print(acc)

one()
two()
