X31: plusOut
Write a function in Java that implements the following logic:
Given a string str and a non-empty word, return a version
of the original string where all chars have been replaced by
pluses (+), except for appearances of the word which
are preserved unchanged.
Examples:
plusOut("12xy34", "xy") -> "++xy++"
plusOut("12xy34", "1") -> "1+++++"
