137. In mathematics, a perfect number is a type of integer. The procedure IsPerfect (num) returns true if num is a perfect number and returns false otherwise. The following program is intended to count and display the number of perfect numbers between the integers start and end, inclusive. Assume that start is less than end. The program does not work as intended Line 1: currentNum + start Line 2: Line 3: count 0 REPEAT UNTIL (currentNum > end) Line 4: Line 5: count count + 1 Line 6: IF (IsPerfect (currentNum)) Line 7: { Line 8: count + count + 1 Line 9: currentNum + currentNum + 1 Line 10: Line 11: currentNumt currentNum + 1 Line 12: Line 13: DISPLAY (count) Which two lines of code should be removed so that the program will work as intended? Select two answers. (A) Line 5 (B) Line 8 (C) Line 9 (D) Line 11

Computer Science Assume you are a software developer that has written a system that analyses pictures of various recyclable items (such as a can, bottle or a crate). It can be used via a Web Application (Web API), i.e., the users send pictures over the Internet. The system returns for each picture how many of each item are seen in the picture.
