Write a program to accept a sentence and print all the unique words present in the string.
If none of the characters present in the string are repeated, then it is called a Unique String.

Sample Output: IS THE OF WEST BENGAL

for(int i=1;i<s.length();i++)
{
if(pc==s.charAt(i))
{
c++;
pc=s.charAt(i);
}
else
