Text justification is spacing of the text block so that both right and left side of the text have a straight edge. This is accomplished by adding spaces so that every line is exactly the same length. You are to implement simplified justification rules as follows. Every line should be exactly $90$ characters long $($keep this value in a named constant$).$ To get to this line length, extra space is first added after punctuation marks. You need to consider only these marks: $.,!?$; That is$,$ every punctuation mark may be followed by two spaces unless it is the last character in the line. If the spaces after punctuation marks are added and the line is still less than $90$ characters, additional spaces are added after random words in the line. There is no need to ensure that the extra spaces are spread uniformly. Randomization is sufficient. A line that is shorter than $40$ characters is considered the end of a paragraph is not justified. Hyphenation $($breaking up of words$)$ between lines is not required.
