Combine an Array into a String Using the join Method

Combine an Array into a String Using the join Method

---

Problem Explanation

Use the join method (among others) inside the sentensify function to make a sentence from the words in the string str. The function should return a string. For example, "I-like-Star-Wars" would be converted to "I like Star Wars". For this challenge, do not use the replace method.
