DIY Challenge 3: The jumping frog
A frog jumps along a number line starting at 0. The first jump takes him it 1 unit, the second jump is 2 units, and so on. Each jump can take it to the right or to the left.
Can you find a way so that the frog ends up at the starting position after exactly 10 jumps?
