To reverse a string , we need to loop the string and iterate backwards on it.
while iterating save the characters into a temporary string.
Finally return the reversed string.
Note : String class in Java does not have reverse() method, however StringBuilder class has built in reverse() method. StringBuilder class do not have toCharArray() method, while String class does have toCharArray() method.
To find duplicate words , we need to use Hashmap and store all the words as keys.
now we can take count of the words.
once count has been taken , we know the duplicates.
now , we can eliminate them from the given string.
