有一组整数对，(,, ....,)，用
vector >实现。
现在需要去处所有满足下列条件的数对：
如果piwj，那么去除i
如果pi>pj且wi
保证最后的vector满足上述条件，且没有删除任何不需要删除的元素。
k不大，所以k^3复杂度可以接受。
谢谢大家。 |

发帖数: 7639 | 5 I just put the example code from
http://latex-beamer.sourceforge.net/
and made a ps output, but it generate slide at left-bottom
corner of every page. What is the problem?
by the way, how many page styles I can use and
where I can find the samples of them?

It is brightening much faster than expected. It is already so bright as 6.2
mag (May 14, Marco Goiato). The apparent size is so large as 20 arcmin. It
will pass 0.85 A.U. from the sun in late June, and it may reach up to 4.5
mag. In the Northern Hemipshere, it is observable until around May 25, when
the comet will be 6 mag. It will be unobservable for one and a half month
around the perihelion passage. But it will appear in the morning sky again
at 5.5 m |
