需要注意的是这里的秒 = 时+分+秒，不是分别转化为时分秒

seconds = int(input())
# seconds = 3661 or seconds = 61
secs = seconds % 60
seconds -= secs
hours = seconds // 3600
seconds = seconds - (hours * 3600)
mins = seconds // 60

secs = str(secs)
mins = str(mins)
hours = str(hours)
print(hours + " " + mins + " " + secs + " ")
