Advent of Code 2022: no pato edition

thenanox #91 Dic '22 Virconita

la verdad es que este tipo de problemas, casi siempre son manejos de strings/arrays y hay lenguajes como javascript y python que te dan una facilidad...

lo que pasa que javascript ya no me apetece, y quiero ver que tal aplica go, pero veo que sin ser verboso no es ubercomodo

vamos a por el day2

No se como puede ser tan popular esta competición si al final es solo parsear el input, comparado con el google code o el facebook hacker cup es horrible.

        int score = 0;
        for(String line: input) {
            char oppInput = line.split(" ")[0].charAt(0);
            char myInput = line.split(" ")[1].charAt(0);

Día 3. Pyhton. Oneliner. Parte 1 y 2

Parte 1

print(sum([ord(list(set(x.strip()[:len(x.strip())//2])&set(x.strip()[len(x.strip())//2:]))[0]) - (96 if list(set(x.strip()[:len(x.strip())//2])&set(x.strip()[len(x.strip())//2:]))[0].islower() else 38) for x in open('input.txt')]))

Resumen del código: Por cada línea, parto por la mitad la cadena, convierto cada mitad a un set y les hago un & lógico que te da las letras que se repiten. Con el resultado, utilizo ord() para sacar su valor numérico en ASCII y, dependiendo de si es mayúscula o minúscula, le resto una cantidad distinta para que me de el valor de prioridad correcto que tiene. De esta manera acabo con una lista con los valores de prioridad de cada línea, por lo que con hacer un sum() de la lista ya tienes el resultado correcto

Parte 2

print(sum([ord(list(set(x[0])&set(x[1])&set(x[2]))[0]) - (96 if list(set(x[0])&set(x[1])&set(x[2]))[0].islower() else 38) for x in zip(*(iter([x.strip() for x in open('input.txt')]),)*3)]))

Resumen del código: Aquí parecido, solo que voy formando grupos de 3 con cada línea (ejemplo, [('linea 1','linea 2','linea 3'),('linea 4','linea 5','linea 6')] ) y aplicando la misma lógica que antes, hago set('linea 1') & set('linea 2') & set('linea 3') para sacar la letra que se repite. Teniendo la letra que se repite puedo hacer como antes y sacar el orden de prioridad y sumar la lista resultante
