LearnStreet Mastermind Game Sample Solution Method 3

function checkAnswerWrongPlace(ans, realanswer){
    // This method compares two input strings representing a player's guess ("ans")
    // at the correct sequence of colored pegs and the actual correct solution
    // ("realanswer"). But instead of returning the correct number of positional
    // matches between the two strings, this method returns the number of
    // character matches between the two strings where the matching characters
    // are not in the same position in both strings: hence "right answer, wrong place".
