1. For the algorithm presented below, what will be displayed in Line 9 given the following input in Line 2?
num1 = 4
num2 = 21
num3 = 14
num4 = 20
1 Prompt for num1, num2, num3, num4
2 Get num1, num2, num3, num4
3 Set index to 1
4 DOWHILE index < 4
5 IF num1 > num2 THEN
Order_two_numbers (num1, num2)
ENDIF
6 IF num2 > num3 THEN
Order_two_numbers (num2, num3)
ENDIF
7 IF num3 > num4 THEN
Order_two_numbers (num3, num4)
ENDIF
8 add 1 to index
ENDDO
9 Display num1, num2, num3, num4
END
Order_two_numbers (number1, number2)
10 temp = number1
11 number1 = number2
12 number2 = temp
END
