Hi Sirisha

Please find the code attached.
 
string inputStr = 'MISSISSIPPI';
set<integer> uniqueSet = new set<integer>();
uniqueSet.addAll(inputStr.getChars());
system.debug('::::::'+string.fromCharArray(new list<integer>(uniqueSet)));

Hi,
A quick solution .Let me know if this helps.
 
string testString='MISSISSIPPI';
list<String> testList=testString.split('');
set<string> uniqueString= new set<string>();
uniqueString.addAll(testList);
String neededString;
for(String s:uniqueString){
    if(neededString !=null){
    neededString+=String.valueOf(s);
    }else{
        neededString=String.valueOf(s);
    }
}
system.debug('neededString  '+neededString);
