Description
To print unique word from a string Step 1: Split the string from space and store it into a array of string to get all words. Step 2: Take two loops one loop is for traversing the array of string. Step 3: Second loop is for checking the duplicate elements, if duplicate element found break the second loop. Step 4: If loop reached to end, print the word. Example: str : this is java and java is good output : this is java and good
