Shoppers at a mall were asked whether they preferred wearing gloves or mittens in cold weather. Shoppers' preferences were stored in the list voteList as strings, with the string "Gloves" representing a preference for gloves and the string "Mittens" representing a preference for mittens. %3D The following code segment is intended to traverse the list and display the number of shoppers who chose gloves and the number of shoppers who chose mittens. numGlovesVotes 0 numMittensVotes 0 IF(vote = "Gloves") } numGlovesVotes numGlovesVotes + 1 { ELSE } numMittensVotes numMittensVotes + 1 { DISPLAY(numGlovesVotes) DISPLAY(" shoppers chose gloves and") DISPLAY(numMittensVotes) DISPLAY(" shoppers chose mittens.") Which of the following should replace so that the code segment works as intended? FOR EACH vote IN voteList a. IF(vote = LENGTH(voteList)) C. %3D REPEAT LENGTH(voteList) TIMES d. REPEAT UNTIL(vote > LENGTH(voteList)) b. 5arrow_forward
- Differentiate between code included inside a sequence structure and code contained within an if structure. Answer:arrow_forwardWhat information is included in the header?arrow_forwardAdd formulas to complete the table of hours used. In cell B17, create a nested formula with the IF and SUM functions that check if the total number of hours worked in week 1 (cells B9:F9) is equal to 0. If it is, the cell should display nothing (indicated with two quote marks: ""). Otherwise, the cell should display the total number of hours worked in week 1. Copy the formula from cell B17 to fill the range B18:B20arrow_forward
