Add conditionals

The while loop that corrects the offset is a good start, but what if offset is negative? You can try to run the sample code on the right where offset is initialized to -6, but your sessions will be disconnected. The while loop will never stop running, because offset will be further decreased on every run. offset != 0 will never become False and the while loop continues forever.

Fix things by putting an if-else statement inside the while loop.

Instructions

  • Inside the while loop, replace offset = offset - 1 by an if-else statement:
    • If offset > 0, you should decrease offset by 1.
    • Else, you should increase offset by 1.
  • If you've coded things correctly, hitting Submit Answer should work this time.
