1) Create a hashtable which won't allow you to have duplicates.
2) Loop thru all characters in the string one at a time.
3) Within loop get the character, check if it is already there in hashtable as a key, then just increment the value by one for that key, else create a new entry in hashtable with key as that character and its value as one.
4) After loop is over get the maximum of all values in the hastable and the corresponding key in hashtable.
