Case contract

Input {'status':[FLOWN|OPEN|NOSHOW per coupon],'fee'}. After the first NOSHOW, every later OPEN coupon becomes VOID (earlier coupons are untouched, FLOWN stays FLOWN). The no-show fee is charged once per ticket. Return [statuses, fee].

Why this case matters

Coupon sequence rules cancel onward segments after a no-show and assess a single penalty.

One recorded failure
