Scala & Spark-Master Big Data with Scala and Spark - Using Maps for Word Count

The video tutorial explains how to create a program that counts user-entered words using a map. It covers adding new words with an initial count and updating the count for existing words. The tutorial includes a demonstration of the program with user input and output, ensuring the functionality works as expected. The video concludes with a summary and a preview of the next video, which will focus on checking word counts.

What is the initial step when a new word is entered by the user?

• Update the existing count

• Add the word with a count of one

• Ignore the word

• Remove the word from the map

How does the program handle a word that is already present in the map?

• It increments the count by one

• It resets the count to zero

• It deletes the word

• It leaves the count unchanged

What happens when the word 'apple' is entered for the second time?

• The count is incremented to two

• The count remains one

• The count is set to zero

• The word is removed from the map

What is printed when a new word is added to the map?

• The word with a count of one

• The word with a count of two

• The word with a count of zero

• Nothing is printed

What is the count of 'apple' after it is entered three times?

• Four

• Two

• One

• Three

What is the next feature to be implemented in the program?

• Checking the count of a specific word

• Allowing the user to delete words

• Adding multiple words at once

• Resetting all counts to zero

What will the program do if a user checks the count of a word not present in the map?

• Add the word with a count of one

• Ignore the request

• Reset the map

• Display a message that the word is not present
