Quando modifichi un post su SE, tutte le altre modifiche entro un periodo di tolleranza di 5 minuti vengono unite in esso. Dato un elenco di volte in cui modifichi un post, conta le modifiche non in un periodo di tolleranza.
Di 'che modifichi in pochi minuti [0,3,4,7,9,10,11,12]. Ciò si traduce in 3 modifiche a volte [0,7,12], mentre il resto accade nei loro periodi di grazia.
0: [3,4]
7: [9,10,11]
12: []
- La prima modifica è al minuto 0. Le modifiche ai minuti 3 e 4 sono entro il suo periodo di tolleranza di 5 minuti, quindi non contano.
- La seconda modifica è al minuto 7. Le modifiche ai minuti 9, 10, 11 sono entro il suo periodo di tolleranza.
- La terza modifica al minuto 12 è appena oltre il limite del periodo di tolleranza di 5 minuti a partire dal minuto 7.
Quindi, l'output è 3.
L'elenco dei tempi in minuti sarà un elenco di numeri interi in aumento. Il primo numero sarà sempre 0 per la pubblicazione iniziale, che contiamo come modifica.
