Allright here's a hint......
Do you really have to carry out the multiplications to find the last digit ?

Example : 9^1 = 9
9^2 = ..1
9^3 = ..9
9^4 = ..1

etc. where .. denotes digits other than last digit.

[cpp] if(factorial == EOF)
break;[/cpp]
Are you sure that works ?

I usually use : [cpp]if(feof(stdin)) break;[/cpp]

People often use the number of fields successfully scanned, returned by scanf(), to terminate their loop.... [cpp]while(scanf("%d",&variable)==1)
{
Dostuffwithvariable();
}[/cpp]

[cpp]if(!m && !m) break;[/cpp]

You probably mean [cpp]if(!m && !n) break;[/cpp]

And I can tell you there are more.....
I wrote close to 150 lines to solve this problem.....takes 0.070 secs.

Thanks a lot for the test cases. A little investigation reavealed you may assume that a triple peak will occur within 21252 days of the given date.

I had assumed 21252 days from beginning of year.

Also, even the extra line that you had mention gave me a WA. However even after I removed that, I ...

Can't imagine why I get WA. Some nice test cases may help if you can't point out my mistake......
#include<iostream.h>

main()
{
int p,e,i,d,z,count=1,cases;

for(cin >> cases;cases--;){
while(1)
{
cin>>p>>e>>i>>d;
if(p==-1) break;

p = p % 23;
e = e % 28;
i = i % 33;

z = (d/33*33)+i ...

Perhaps // before @end_of_source_code is giving trouble.

Remove // from @begin_of_source_code also.

Take care to put both on independant lines.

Nope. Not Longest Common Subsequence. Check out this link, it has some description :

I am still searching for good info on how to solve it.

In the problem History Grading I need to use this algorithm but don't know how. Can someone plese show me how to find LIS from an array of integers (named 'answer') in C code ?

I am 18. Joined very recently. Solved only 5 problems yet. Anybody want to point out the easy questions to me ?

I came across an old post of yours.....if you still need help with Bee Breeding : take a hint from http://onkar.s5.com/codezone .

Oh hell........my mailer yahoo kept adding lines at the end. I included the @end_of_source_code and it compiles now. Thanks for your attention.

I tried to solve the first problem and it runs fine on my computer Win200, Bloodshed Dev C++ without errors. But the online judge says compile error. 01624693_24.c:38: syntax error before `!' . What the hell is wrong ?
