Dada la string alfanumérica str , la tarea es verificar si el conteo de Alfabetos y el conteo de Números son iguales o no.
Ejemplos:
Entrada: str = «GeeKs01234»
Salida: Sí
Explicación:
El recuento de letras y números es igual a 5.Entrada: str = “Gfg01234”
Salida: No
Explicación:
La cuenta del alfabeto es 3, mientras que la cuenta de los números es 5.
Enfoque: La idea es utilizar los valores ASCII de los caracteres para distinguir entre un número y un alfabeto. Después de distinguir los caracteres, se mantienen dos contadores para contar el número de letras y números respectivamente. Finalmente, se comprueba la igualdad de ambos contadores.
Los rangos ASCII de los caracteres son los siguientes:
- Caracteres en minúsculas: 97 a 122
- Caracteres en mayúsculas: 65 a 90
- Dígitos: 48 a 57
A continuación se muestra la implementación del enfoque anterior:
