在范围库中,算法将范围用作参数(不过,如果需要的话,它们也可以使用迭代器)。 它们可以直接对集合进行操作。<algorithm>中可用的范围算法示例包括copy、copy_n、copy_if、all_of、any_of、none_of、find、find_if、find_if_not、count、count_if、for_each、for_each_n、equal和mismatch。
view对于数据的遍历都是lazy evaluation(惰性求值),比如说views::iota(1),表示一个自然数序列(1,2,3,4...)一直到无穷大,这个序列并不是定义的时候就全部产生出来的,而是需要遍历的时候才逐个往后增加的;再比如上面的例子,通过对各种view的数据处理规则定义了一个变量v,此时所有的数据处理都未进行,直到运行copy...

Inline hints for rangesCopy heading link Kotlin supports various ways to declare ranges. However, sometimes understanding range bounds can be more difficult than you would expect. For instance, it can be tough to distinguish between..anduntil. ...
Do not copy such a sheet between workbooks or you will create inter-workbook links. If you prefer to use a 'January' sheet (say) as the template for 'February' etc, avoid any defined names that are scoped to the workbook, use only sheet-scoped names. The named Lambda functions should ...
