An algorithm is shown in the pseudocode below:

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

What will be the first value output when the user inputs 18?
