        for (var a = 0; a < arr[i].length; a++) {
            var countNew = 0;
            for (var b = a + 1; b < arr[i].length; b++) {
                if (arr[i][a] === arr[i][b])
                    countNew += 1;
            }
            if (countNew > count) {
                count = countNew;
                word = arr[i];
            }
        }
    }
    return word;
}
