算法学习建议(转)

一般要做到50行以内的程序不用调试、100行以内的二分钟内调试成功.acm主要是考算法的
,主要时间是花在思考算法上,不是花在写程序与debug上。
下面给个计划你练练:
第一阶段:
练经典常用算法,下面的每个算法给我打上十到二十遍,同时自己精简代码,
因为太常用,所以要练到写时不用想,10-15分钟内打完,甚至关掉显示器都可以把程序打
出来.
1.最短路(Floyd、Dijstra,BellmanFord)
2.最小生成树(先写个prim,kruscal要用并查集,不好写)
3.大数(高精度)加减乘除
4.二分查找. (代码可在五行以内)

半数循环时用减法法代替乘法(2012-01-31 00:25:00)
摘要:做循环的时候,如果条件是
a=0;a<=b/2;a++;
由于加减运算比乘除运算更快,可以取代为
a=0;a<=b-a;a++;......

Sublime Text Menu Problem(2012-01-30 23:44:00)
摘要:After intalling ST2, I click <hide menu> and then it seems be gone for ever.
<F10> doesn't work.
Then I download ST1.4, and click Preferences->General Preferences.
Then a new tab pops up.
It must be the configurations file, I think.
Its path is:
C:\Users\Line\AppData\Roaming\SublimeText\Packages\Default\Options\Application.sublime-options
Then I go to
C:\Users\Line\AppData\Roaming\Sublime Text
2\Settings\Session.sublime_session
and change all the <"menu_visible": false> into <"menu_visible": true>.
And problem solved!......
2010程序设计期末试题(2012-01-30 23:23:00)
摘要: 7.
After a is initialized, which of the following expressions CANNOT access the face component of a correctly?
struct card{
char *face;
char *suit;
} a, *aPtr = &a;
(A) a.face
(B) aPtr->face
(C) (*aPtr).face
(D) &a->face My answer: C
Correct answer: D
Select all to see the answers and the tips
Tips: just consider *aPtr as a, they are totally
equivalent. Similarily, a[i] is the same as *(a+i). so a[i][j] is the same as
*(a+i)[j]
See T10
10. For int a[3][4], (*p)[4]=a; Which of the
following CANNOT access a[i][j]
correctly?
(A) *a[i]+j
(B) (*(p+i))[j]
(C) p[i][j]
(D) *(*p+4*i+j)
answer:A......
