【每日一题20220830】友好展示持续的时长

hogwarts_wenzi · 2022 年8 月 30 日 02:57

写一个函数，接收秒数，处理成人类友好的方式格式化持续时间。

该函数必须接受一个非负整数。如果它是零，它只是返回"now" 。否则，持续时间表示为years 、days 、hours 、minutes 和seconds 的组合。

举个例子就更容易理解了：

* For seconds = 62, your function should return 
    "1 minute and 2 seconds"
* For seconds = 3662, your function should return
    "1 hour, 1 minute and 2 seconds"

就本题而言，一年是 365 天，一天是 24 小时。

请注意，空格很重要。

细则

生成的表达式由 4 seconds、 1 year等分量组成，一个正整数和一个有效的时间单位之一，由空格分隔。如果整数大于 1，则时间单位以复数形式使用。

组件由逗号和空格 ( ", " ) 分隔。除了最后一个组件用 " and " 分隔，就像用英文写的一样。

1 second and 1 year 不是正确的，而 1 year and 1 second 是正确的。

不同的组件有不同的时间单位。所以 5 seconds and 1 second 这样的重复单位写法是错误的。

如果组件的值恰好为零，则组件根本不会出现。因此，1 minute and 0 seconds 是无效的，应该是1 minute 这样编写。

必须“尽可能”使用一个时间单位。这意味着该函数不应该返回61 seconds ，而是应该返回1 minute and 1 second 。所以不要出现366天、24小时、60分、60秒这样的数据。

这断言结果确定没有问题？就33243586而言
46+19*60+18*60*60+19*24*60*60+1*366*24*60*60 ?= 33243586
