Under the ship, he printed in big red letters: C-O-N-G-R-A-T-U-L-A-T-I-O-N-S!
在船下面,他用红色大字写着:C-O-N-G-R-A-T-U-L-A-T-I-O-N-S!
Thus, for a typical program invocation with N options, the code needs only O(N) [N*O(1)] comparisons—an order of magnitude improvement over the legacy code.
因此,对于具有N 个选项的典型程序调用,代码只需执行O(N) [N*O(1)]比较 —这是对遗留代码的巨大改进。
As I mentioned in the overview section, random character access on a rope with many internal nodes is approximately o (log n), so traversal is o (n log n).
就像我在概述一节中提到过的,在拥有许多内部节点的rope上随机访问字符的时间大约为o (logn),所以遍历时间为o (nlog n)。
Merge sort has o (n log n) worst-case and average-case performance.
合并排序的最差性能和平均性能为o (nlog n)。
For example, if the complexity order of the current technique is O(n**2), speeding up the steps by 10x is a lot less helpful than finding an O(n) substitute.
例如,如果当前技术的复杂性等级是O(n**2),那么将这些步骤加速10倍远不及寻找 O(n) 替代品来得有用。
Listing 2's implementation runs in o (n) time. I won't prove this, but the running time of Listing 1's naive, recursive implementation is exponential in n.
清单2中的实现所需的时间比清单1短许多,清单2的运行时间为O (n),而清单1中的递归实现的运行时间是n的指数。
Using this notation, you should know that search through a list is O(n) and binary search (through a sorted list) is log(n).
看到这个标记你就应该知道搜索链表的复杂度为O(n),进行二进制搜索时(已排序)的空间复杂度为log(n)。
The simple sugars monosaccharides0 are basically aliphatic polyhydroxy aldehydes and ketones: HOCH2 - CHOH n-CHO and HOCH2 - CHOOH n-1-C-O-Ch2OH, called "aldoses" and "ketoses," respectively.
单糖本质上是脂族的多羟基醛和酮,即HOCH2- (CHOH) 2 -CHO和HOCH 2 - (CHOH) n - 1 - C: O - CH 2 OH,分别称为醛糖和酮糖。
There are two sorted arrays A and B of size mand n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)).
这个题是求两个有序数组的中间数,其实这个中间数,如果是奇数,就是中间的那个数,如果是偶数,就是中间的两个数的和的平均值。
