Advent of Code 2023 Day 15

— Day 15: Lens Library —

A reindeer needs your help to process the Holiday ASCII String Helper algorithm.

Run the HASH algorithm on each step in the initialization sequence. What is the sum of the results? (The initialization sequence is one long line; be careful when copy-pasting it.)

with open('data-2023-15.txt', 'r') as f:
    inp = f.read().splitlines()

Maybe write an explanation of the solution approach here

mult = 17
div = 256
summer = 0


for i in inp:
    val = 0
    for j in i: 
        val += ord(j)
        val *= mult
        val = val % div
    summer += val
    
summer

# 510388

— Part Two —

There is a second part to the instructions, of course.

With the help of an over-enthusiastic reindeer in a hard hat, follow the initialization sequence. What is the focusing power of the resulting lens configuration?
