Scala & Spark-Master Big Data with Scala and Spark - Solution (Basic Functions)

The video tutorial guides viewers through solving a quiz problem by writing a function that takes two numbers as input and returns the greater one. It covers taking user input, casting it to integers, writing the function with proper logic using if statements, and calling the function to get the desired output. The tutorial emphasizes common mistakes like forgetting to call the function and provides a step-by-step approach to ensure the solution works correctly.

What is the primary task described in the problem statement?

• To write a function that returns the greater of two numbers.

• To write a function that multiplies two numbers.

• To write a function that subtracts two numbers.

• To write a function that adds two numbers.

What is the first step in handling user input as described in the video?

• Convert the input to a boolean.

• Convert the input to an integer.

• Convert the input to a float.

• Convert the input to a string.

Which keyword is used to define a function in the programming language discussed?

• def

• func

• function

• define

What is the purpose of the if statement in the function?

• To check if the first number is not equal to the second.

• To check if the first number is greater than the second.

• To check if the first number is equal to the second.

• To check if the first number is less than the second.

What common mistake is highlighted when writing functions?

• Forgetting to use parameters.

• Forgetting to return a value.

• Forgetting to call the function.

• Forgetting to define the function.

What happens when a return statement is executed in a function?

• The function pauses execution.

• The function terminates immediately.

• The function restarts from the beginning.

• The function continues to execute the remaining lines.

What is the expected output when the function is called with inputs 10 and 50?

• 50

• 0

• 10

• 60
