Day 10

Part 1

• Read in input file

with open("day10/input.txt") as f:
    input = f.read().splitlines()

First 100 lines of input looks like this:

['addx 2',
 'addx 3',
 'addx 3',
 'addx -2',
 'addx 4',

• Create a generator that returns the totals each time it iterates

• Finally the answer for the top 1 given the input

strengths = sum_strengths(input)
print(f'the correct answer for part 1 is {strengths}')

the correct answer for part 1 is 14540

Part 2

cpu = CPU(input)
pixels = list(cpu.draw_pixel())
for i in range(0,240,40):
    row = pixels[i:i+40]
    s = "".join(row)
    print(s)

print("EHZFZHCZ")
