Choose a reason for hiding this commentThe reason will be displayed to describe this comment to others.Learn more. estás añadiendo la palabra a la variable sum, le estás diciendo que por ejemplo en la primera iteración "seat", sum += "0seat", luego "correspond", por lo que en la segunda iteración vale "0seatcorrespond" y así sucesivamente.

There was a problem hiding this comment. Choose a reason for hiding this commentThe reason will be displayed to describe this comment to others.Learn more. estás volviendo a declarar la variable con el nombre differ, por lo que estás sobreescribiendo la variable de la línea 51. si quieres asignar un valor a la variable de arriba deberías hacerlo sin la palabra reservada var | ||

There was a problem hiding this comment. Choose a reason for hiding this commentThe reason will be displayed to describe this comment to others.Learn more. en esta linea le estás diicnedo que "words" que es el array que estás iterando, vale la primera palabra del array en la primera iteración, por lo que luego el bucle iterará solo por las letras de esta palabra | ||
