The instant unlike binary search, where each instance was separate, here the instances overlap.
这个例子不像搜索二进制数,每个例子是独立的,这里的例子是相互重叠的。
The bits are still there, much like bits are still left when you erase a file on your hard disk but they're forgotten about.
二进制数还在那里,就像你在硬盘上删除一个文件,二进制还在那里,但是它们被遗忘了。
Remember, we saw that last time looking at the binary numbers. 2 to the n is a big number.
还记得吗,我们上次看过的二进制数,从2到n是一个很大的数。
Seventy-nine. In fact, if you add up each of these numbers, 9 you should get the decimal number 79 79 from this binary number here.
9,事实上,如果你把这些数字累加,你应该能从这些二进制中9,得到十进制数。
to the n, every value in the 1 bit vector we looked at last time is either 0 or 1. So it's a binary n number of n bits, 2 to the n.
从2到n,我们上次看到的,位向量的每个值不是0就是,所以它是n,比特的二进制数,从2到。
