Question 42

An algorithm is represented by the following pseudo-code:

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

What is the value of the variable trips immediately after the inner WHILE loop finishes when the user input is 240?
