After the loop is done, we push the length of the data at the end of the list.

循环完成后，我们将数据的长度压入到序列的尾部。

zero() is slowest, because the JIT can't yet optimize away the cost of getting the array length once for every iteration through the loop.

zero() 是当中最慢的，因为对于这个遍历中的历次迭代，JIT并不能优化获取数组长度的开销。

The for loop iterates over the list of substrings, printing out each substring and its length.

for 循环迭代子字符串 list，打印每个子字符串及其长度。

Well, this question mark becomes an O, this question mark becomes an O, and then the loop terminates 0 1 2 because it's iterating from zero to N so that's zero, 1, 2 and the length of the string is 3 so the loop terminates, but I remember that I needed to have this special sentinel value so I'm just going to put it there manually.

嗯，这个问号变成了，这个问号变成了0，然后循环结束了,以为迭代从0到N，那就是，字符串的长度是3，然后循环就结束了，但是我记得我需要这个特殊的标记值,所以需要手动的加上它。

He piggybacks this unit directly on top of a scope, allowing him to produce never-before-captured wide-field images, like his striking, ghostly picture of Barnard's Loop-a huge arc of gas that covers the length of the constellation Orion.
