Hi,
I am working on below challenge
http://codingbat.com/prob/p170829
I tried my code as below
public String plusOut(String str, String word) {
return str.replaceAll(".word.","+word+");
  
}
I am getting below result
Expected      Run            
plusOut("12xy34", "xy") → "++xy++"      "12xy34"      X         
plusOut("12xy34", "1") → "1+++++"      "12xy34"      X         
plusOut("12xy34xyabcxy", "xy") → "++xy++xy+++xy"      "12xy34xyabcxy"      X         
plusOut("abXYabcXYZ", "ab") → "ab++ab++++"      "abXYabcXYZ"      X         
plusOut("abXYabcXYZ", "abc") → "++++abc+++"      "abXYabcXYZ"      X         
plusOut("abXYabcXYZ", "XY") → "++XY+++XY+"      "abXYabcXYZ"      X         
plusOut("abXYxyzXYZ", "XYZ") → "+++++++XYZ"      "abXYxyzXYZ"      X         
plusOut("--++ab", "++") → "++++++"      "--++ab"      X         
plusOut("aaxxxxbb", "xx") → "++xxxx++"      "aaxxxxbb"      X         
plusOut("123123", "3") → "++3++3"      "123123"      X
