Alessandra Wu · Answer 1

a) the sum is correctly computed

Explanation:

The syntax of the program is also correct and the variables are declared and initialized in a properly effective and efficient manner. Therefore, we can conclude that the sum will be displayed correctly in the screen and no exceptions will appear.

Israel Martinez · Answer 2

a. The sum is correctly computed

Explanation:

Entering this function;

Counter = 0 rdd = sc. parallelize (data) def increment_counter (x) : global counter counter + = x rdd. foreach (increment_counter) print ("computed sum: ", and running the program produced the correct calculation for the sum.

This entails that The syntax of the program is also correct and the variables are declared and initialised properly.
