This was the question asked by one of the interviewers. I thought of using a File operations like use a stream reader to read each word with space as a dilimeter and increase the count for each word but am not very sure how to implement a delimeter in my code?
OR
I think while reading word store them in an string /arraylist and find the length of the arraylist.
Which option you think is more optimized in terms of memory and other factors.
Any pointers/suggestions are higly appreciate.
