Dado un número hexadecimal como entrada, la tarea es convertir ese número en un número binario.
Ejemplos:
Input: Hexadecimal = 1AC5
Output: Binary = 0001101011000101
Explanation:
Equivalent binary value of 1: 0001
Equivalent binary value of A: 1010
Equivalent binary value of C: 1100
Equivalent binary value of 5: 0101
Input: Hexadecimal = 5D1F
Output: Binary = 0101110100011111
Enfoque: un número hexadecimal es un sistema de numeración posicional con una raíz o base de 16 y utiliza dieciséis símbolos distintos.
Un número binario es un número expresado en el sistema numérico binario de base 2, que utiliza solo dos símbolos: 0 (cero) y 1 (uno).
Para convertir un número hexadecimal a binario, el equivalente binario de cada dígito del número hexadecimal se evalúa y se combina al final para obtener el número binario equivalente.
A continuación se muestra la implementación del enfoque anterior:
