a single string that's the concatenation $("$putting together"$)$ of all the strings in an$\_$array, except a$\_$string is inserted in between each string.

Question $3.$ Use the array book$\_$title$\_$words and the method join to make two strings $(4$ Points$)$:

"Eats, Shoots, and Leaves" $($call this one with$\_$commas $)$

"Eats Shoots and Learts" $($call this one without$\_$commas$)$

Hint: If you're not sure what join does, first try just calling, for example, "data$8".$ join$($book$\_$title$\_$words$).$
