tło
Królewski Holenderski Instytut Meteorologiczny definiuje falę upałów * jako serię co najmniej 5 kolejnych dni o temperaturze ≥25 ° C („pogoda letnia”), tak że co najmniej 3 z tych dni to ≥30 ° C („pogoda tropikalna” ).
Tropikalnej pogody nie trzeba mierzyć kolejno: na przykład: 30, 25, 30, 26, 27, 28, 32, 30
8-dniowa fala upałów z 4 dniami tropikalnej pogody.
* (Cóż, według holenderskich standardów.)
Wyzwanie
Biorąc pod uwagę niepustą listę dodatnich liczb całkowitych reprezentujących pomiary temperatury Celsjusza z kolejnych dni, zdecyduj, czy ta lista zawiera falę upałów (zgodnie z powyższą definicją).
Najkrótsza odpowiedź w bajtach wygrywa.
