Advent of Code 2022 Day 6

Part 1 (Scala)

def part1(input: String) = {
  val index = input
    .toCharArray()
    .sliding(4)
    .zipWithIndex
    .map((chars, i) => (chars, i + 4))
    .find((chars, _) => chars.distinct.length == 4)
    .head
    ._2;
  println("Day 6 Part 1: " + index);
}

Part 1 (Rust)

fn part_1(input: &str) {
    let index = input
        .as_bytes()
        .windows(4)
        .enumerate()
        .map(|(i, byte)| (i + 4, byte.iter().collect::<HashSet<_>>()))
        .find(|(_, set)| set.len() == 4)
        .unwrap()
        .0;
    println!("Day 6 Part 1: {index}")
}

Part 2 (Scala)

其實就是改變 Part 1 的數字而已啊 😂

def part2(input: String) = {
  val index = input
    .toCharArray()
    .sliding(14)
    .zipWithIndex
    .map((chars, i) => (chars, i + 14))
    .find((chars, _) => chars.distinct.length == 14)
    .head
    ._2;
  println("Day 6 Part 2: " + index);
}

Part 2 (Rust)

一樣，就只是改變 Part 1 的數字而已 😂

fn part_2(input: &str) {
    let index = input
        .as_bytes()
        .windows(14)
        .enumerate()
        .map(|(i, byte)| (i + 14, byte.iter().collect::<HashSet<_>>()))
        .find(|(_, set)| set.len() == 14)
        .unwrap()
        .0;
    println!("Day 6 Part 2: {index}")
}
