Implementar la tabla de orden

Resumen: 1 tabla de secuencia es la matriz familiarizado bueno en acceso aleatorio,
2. una ubicación dada puede eficientemente adquirir / modificar el valor de tiempo especificado complejidad ubicación es O (1)
3. orden por búsqueda en la tabla de valor, inserción , eliminación, tiempo de complejidad de O (N)
4. para la cola y la cola eliminan interpolación, el tiempo de complejidad de O (1)
