Saat Anda mengedit posting di SE, suntingan lebih lanjut dalam tenggang waktu 5 menit digabungkan ke dalamnya. Diberikan daftar waktu Anda mengedit posting, hitung hasil edit tidak dalam tenggang waktu.
Katakanlah Anda mengedit pada menit [0,3,4,7,9,10,11,12]. Ini menghasilkan 3 suntingan pada waktu [0,7,12], dengan sisanya terjadi pada masa tenggang mereka.
0: [3,4]
7: [9,10,11]
12: []
- Suntingan pertama adalah pada menit ke-0. Suntingan pada menit 3 dan 4 berada dalam tenggang waktu 5 menit, jadi jangan dihitung.
- Suntingan kedua pada menit 7. Suntingan pada menit 9, 10, 11 berada dalam tenggang waktu.
- Suntingan ketiga pada menit 12 baru saja melewati tepi periode tenggang 5 menit mulai dari menit 7.
Jadi, outputnya adalah 3.
Daftar waktu dalam hitungan menit akan menjadi daftar bilangan bulat yang bertambah. Angka pertama akan selalu 0 untuk posting awal, yang kami hitung sebagai hasil edit.
