Refer to the algorithm shown in the pseudocode below:

1  keepGoing ← True
2  WHILE keepGoing = True
3      num ← USERINPUT
4      IF num > 0 THEN
5          count ← 0
6          WHILE num > 0
7              num ← num DIV 4
8              count ← count + 1
9          ENDWHILE
10     ELSE
11         keepGoing ← False
12     ENDIF
13     OUTPUT num
14 ENDWHILE

What is the largest possible value of the variable count when the user input is 80?
