StringBuilder builderWord = new StringBuilder(word);
for(int index=0; index < builderWord.length(); index++) {
    for(int reverseIndex=builderWord.length()-1; reverseIndex > index;reverseIndex--) {
        if (builderWord.charAt(reverseIndex) == builderWord.charAt(index)) {
            builderWord.deleteCharAt(reverseIndex);
        }
    }
}
return builderWord.toString();
