Question

2 multiple choice 1 point you are given a data set in the file finance.csv with the following column names: year, month, revenues, costs, and profits. your manager asked you to find the total costs using repeat loop. which following algorithm could you use? initialize the total_costs, and index; repeat loop; update the index and total_costs initialize the total_costs, and index; repeat loop; update the index and total_costs and break statement in the loop body initialize the total_costs, repeat loop initialize the total_costs; repeat loop; update the total_costs and next statement in the loop body

Explanation:

Step1: Analyze loop requirements

To calculate total costs using a repeat loop, we need to initialize a variable (total_costs) to store the cumulative sum. Also, if the data is in an iterable structure (like a list of rows in a CSV - which can be indexed), we need an index to iterate through the data.

Step2: Consider loop body actions

In the loop body, for each iteration, we need to update the total_costs (by adding the current row's cost value) and update the index (to move to the next row). A break statement is not needed as we want to iterate through all relevant data (assuming we are summing all costs). A next statement is also not relevant in the general logic of summing all elements in a loop for this basic case.

Answer:

Initialise the total_costs, and index; repeat loop; update the index and total_costs
