Dados cuatro números enteros ‘a’, ‘b’, ‘y’ y ‘x’, donde ‘x’ solo puede ser cero o uno. Tu tarea es la siguiente:
- Si ‘x’ es cero asigne el valor ‘a’ a la variable ‘y’
- Si ‘x’ es uno, asigne el valor ‘b’ a la variable ‘y’.
No está permitido utilizar ningún operador condicional (incluido el operador ternario).
Ejemplos:
Input : a = 3, b = 7, x = 1 Output : y = 7 Input : a = 3, b = 7, x = 0 Output : y = 3
La idea es crear una array de tamaño dos donde el primer elemento sea ‘a’ y el segundo elemento sea ‘b’. Usamos x como un índice en la array.
