Saved a checkpoint:

Fixed parts which were wrong but several questions could be improved with more useful advice or additional randomisation.

Chris Graham commented on Question 23 summation for loop 9 years, 2 months ago

Not a very interesting question for practice, as once you know the trick it requires no thought. Could use some additional variables in the loop to make it more interesting.

Chris Graham commented on Question 22 else if 9 years, 2 months ago

Could be improved with randomisation. The answer is always 2.

Could be improved with randomisation. The function always returns true.
