Lorsque vous modifiez une publication sur SE, toutes les modifications ultérieures dans un délai de grâce de 5 minutes y sont fusionnées. Étant donné la liste des fois où vous modifiez un message, comptez les modifications qui ne sont pas dans un délai de grâce.
Disons que vous modifiez en quelques minutes [0,3,4,7,9,10,11,12]
. Il en résulte parfois 3 modifications [0,7,12]
, le reste se produisant pendant leurs périodes de grâce.
0: [3,4]
7: [9,10,11]
12: []
- La première modification est à la minute 0. Les modifications aux minutes 3 et 4 sont dans sa période de grâce de 5 minutes, et donc ne comptent pas.
- La deuxième modification est à la minute 7. Les modifications aux minutes 9, 10, 11 sont dans sa période de grâce.
- Le troisième montage à la minute 12 est juste après le bord de la période de grâce de 5 minutes commençant à la minute 7.
Donc, la sortie est 3.
La liste des temps en minutes sera une liste d'entiers croissants. Le premier nombre sera toujours 0 pour la publication initiale, que nous comptons comme une modification.
