Dado un número x y dos dígitos d1 y d2, reemplaza d1 con d2 en x.
Ejemplos:
Input : x = 645, d1 = 6, d2 = 5 Output : 545 We replace digit 6 with 5 in number 645. Input : x = 746, d1 = 7, d2 = 8 Output : 846
Recorremos todos los dígitos de x. Para cada dígito, verificamos si es d1, actualizamos el resultado en consecuencia.
