The phrasing might be a bit ambiguous, as magnitude swing could also be thought of as delta(i-1)-delta(i) instead of just delta(i). Nonetheless fun problem!
Flawed solution; fails (for example) when 0
Officially not correct because it assumes that the first entry of x is 1, which is true for all testcases
Flawed solution; fails when delta(1)<0, or when 0
This is genius lololol
great solution Gwendolyn
