Case contract

Input {'season','rows':[[arm, adults, children, lap infants]],'bags':[[arm,count]]}. Standard weights: adult 190/195, child 82/87 (summer/winter); lap infants weigh 0 (included with the adult); bags 28 lb. Rows are numbered from 1; more than 3 seated (adults+children) -> 'ERR_ROW_<n>_SEATS'; more infants than adults -> 'ERR_ROW_<n>_INFANTS'. Return [weight, moment r1].

Why this case matters

Standard passenger weights vary by season and passenger type; lap infants do not occupy seats but require an accompanying adult.

One recorded failure
