Ignore cases where there is no char before or after the word, and a char may be included twice if it is between two words. Do not do any printing. for input of "abcXY123XYijk", "X" for input of "XY123XY", "XY""13 for input of "XY1xy", "xY""11" "c13i" 2 THE PLUS OUT PROBLEM Given a string and a non-empty word string, set result to a version of the original string where all chars have been replaced by pluses ("+"), except for appearances of the word string which are preserved unchanged. for input of "12xy34", "Xy", "++xy++" . for input of "12xy34", "1" -"1+ . for input of "12xy34xyabcxy", "xy" "++xy++xy xy
