||
| ## Setup | ||
|
|
||
| ```{r setup} | ||
| # Libraries | ||
| library(tidyverse) | ||
| library(unglue) | ||
| # Read input from file | ||
| input <- read_lines("../input/day17.txt", skip_empty_rows = TRUE) |> | ||
| unglue_data(patterns = c( | ||
| "{label}: {value}" | ||
| )) | ||
| ``` | ||
|
|
||
| ## Part 1 | ||
|
|
||
| Initialize the machine from the text input: | ||
|
|
||
| ```{r} | ||
| program <- input |> | ||
| filter(label == "Program") |> | ||
| pull(value) |> | ||
| str_split_1(",") |> | ||
| as.integer() | ||
| A <- input |> | ||
| filter(label == "Register A") |> | ||
| pull(value) |> | ||
| as.integer() | ||
| B <- input |> | ||
| filter(label == "Register B") |> | ||
| pull(value) |> | ||
| as.integer() | ||
| C <- input |> | ||
| filter(label == "Register C") |> | ||
| pull(value) |> | ||
| as.integer() | ||
| machine <- list(program = program, A = A, B = B, C = C, pointer = 0L, output = NULL) | ||
| ``` | ||
|
|
||
| Define machine's helper functions: | ||
|
|
||
| ```{r} | ||
| combo <- function(machine, operand) { | ||
| case_match(operand, | ||
| 0 ~ 0, | ||
| 1 ~ 1, | ||
| 2 ~ 2, | ||
| 3 ~ 3, | ||
| 4 ~ machine$A, | ||
| 5 ~ machine$B, | ||
| 6 ~ machine$C | ||
| ) | ||
| } | ||
| run_opcode <- function(machine, opcode, operand) { | ||
| func <- case_match(opcode, | ||
| 0 ~ "adv", | ||
| 1 ~ "bxl", | ||
| 2 ~ "bst", | ||
| 3 ~ "jnz", | ||
| 4 ~ "bxc", | ||
| 5 ~ "out", | ||
| 6 ~ "bdv", | ||
| 7 ~ "cdv" | ||
| ) | ||
| get(func)(machine, operand) | ||
| } | ||
| run_machine <- function(machine) { | ||
| while (machine$pointer < length(machine$program)) { | ||
| opcode <- machine$program[machine$pointer + 1] | ||
| operand <- machine$program[machine$pointer + 2] | ||
| machine <- run_opcode(machine, opcode, operand) | ||
| } | ||
| print(machine$output) | ||
| } | ||
| ``` | ||
|
|
||
| Define the opcode functions: | ||
|
|
||
| ```{r} | ||
| adv <- function(machine, operand) { | ||
| machine$A <- floor(machine$A / 2^combo(machine, operand)) | ||
| machine$pointer <- machine$pointer + 2 | ||
| return(machine) | ||
| } | ||
| bxl <- function(machine, operand) { | ||
| machine$B <- bitwXor(machine$B, operand) | ||
| machine$pointer <- machine$pointer + 2 | ||
| return(machine) | ||
| } | ||
| bst <- function(machine, operand) { | ||
| machine$B <- combo(machine, operand) %% 8 | ||
| machine$pointer <- machine$pointer + 2 | ||
| return(machine) | ||
| } | ||
| jnz <- function(machine, operand) { | ||
| if (machine$A != 0) | ||
| machine$pointer <- operand | ||
| else | ||
| machine$pointer <- machine$pointer + 2 | ||
| return(machine) | ||
| } | ||
| bxc <- function(machine, operand) { | ||
| machine$B <- bitwXor(machine$B, machine$C) | ||
| machine$pointer <- machine$pointer + 2 | ||
| return(machine) | ||
| } | ||
| out <- function(machine, operand) { | ||
| machine$output <- str_c( | ||
| machine$output, | ||
| combo(machine, operand) %% 8, | ||
| sep = "," | ||
| ) | ||
| machine$pointer <- machine$pointer + 2 | ||
| return(machine) | ||
| } | ||
| bdv <- function(machine, operand) { | ||
| machine$B <- floor(machine$A / 2^combo(machine, operand)) | ||
| machine$pointer <- machine$pointer + 2 | ||
| return(machine) | ||
| } | ||
| cdv <- function(machine, operand) { | ||
| machine$C <- floor(machine$A / 2^combo(machine, operand)) | ||
| machine$pointer <- machine$pointer + 2 | ||
| return(machine) | ||
| } | ||
| ``` | ||
|
|
||
| Run on puzzle input: | ||
|
|
||
| ```{r} | ||
| run_machine(machine) | ||
| ``` | ||
|
|
||
