UberFULLTIMEPHONE SCREEN

Given an array of words and an integer maxWidth, format the words into lines of exactly maxWidth characters.

Pack each line greedily with as many words as fit, counting at least one space between adjacent words.
For every non-final line with at least two words, distribute spaces as evenly as possible. When they do not divide evenly, earlier gaps receive one extra space.
Left-justify the final line and every single-word line: place one space between words and pad the right side with spaces.

Return the formatted lines in order. Input words contain no spaces, and every word fits within maxWidth.

fullJustify(words: String[], maxWidth: int) → String[]

words = ["This","is","an","example","of","text","justification."]maxWidth = 16return = ["This    is    an","example  of text","justification.  "]

The first two lines are fully justified to width 16. The final single-word line is padded on the right.

words = ["What","must","be","acknowledgment","shall","be"]maxWidth = 16return = ["What   must   be","acknowledgment  ","shall be        "]

The long middle word forms a single-word line, and the final line uses one internal space plus right padding.

words = ["a"]maxWidth = 3return = ["a  "]

The only line is the final line, so the word is followed by two padding spaces.
