Word Lengths in Scala

Given an ArrayBuffer of strings words, return an ArrayBuffer of integers with the length of every word, in the same order as the words.

The length of a word is the number of letters it has.

Example 1:

Input: words = ["I", "love", "pancakes"]
Output: [1, 4, 8]
Explanation: "I" has 1 letter, "love" has 4 and "pancakes" has 8.

Example 2:

Input: words = ["banana", "kiwi", "fig"]
Output: [6, 4, 3]
Explanation: The lengths keep the order of the words: first "banana", then "kiwi", then "fig".

Example 3:

Input: words = ["code"]
Output: [4]
Explanation: One word gives one length.

Constraints:

• words has at least one word.
• Every word is made of English letters, lowercase or uppercase.
• The result has one length per word, in the same order as words.
