Dear UVA staff! I lost my password, but your link http://icpcres.ecs.baylor.edu/onlinejudge/index.php?option=com_comprofiler&task=lostPassword DOES NOT work! I wrote a lot of times to "Contact us" http://icpcres.ecs.baylor.edu/onlinejudge/index.php?option=com_contact&Itemid=4 but N...

Why Time Limit? How to improve solution? #include <stdio.h> #include <memory.h> #define MAX 202 #define INF 1000000000 #define min(i,j) (i<j)?i:j int m,n,a,b,d,cap,i; int MaxFlow,flow; int g[MAX][MAX],used[MAX]; int aug(int x,int t,int CurFlow) { if (x == t) return CurFlow; if (used[x]++) return 0; ...

Why Run Time Error? (Sorry, I can't use HTML) #include <cstdio> #include <vector> #include <string> #include <algorithm> using namespace std; char s[101]; vector<char> op,var; vector<char>::iterator iter; string res; int f(char a, char b) { if (a == 'N') return 1; if (b == 'N') return 0; return a < ...

Your code has a lot of WA:
1. input: w
your program says: w
But 'w' is not WWF, only p,q,r,s,t!

2. input: qwerty
your program says: no WFF possible
But we can find a subset of WWF, for example: t.

I have RTE, but can't find why.
I did a lot of testing.
I tried to put char s[100000]; but it didn't help

Thanks, acc

To asif_rahman0: You cave wrong answer on test 3 40 50 50 40 40 40 0 50 41 Your program gives 30, but answer is 9. I have TLE. Here is my program: #include <stdio.h> #include <memory.h> #define MAX 1500 int m[2][2*MAX+3]; int i,j,k,n,num; void main(void) { while(scanf("%d",&n),n) { mem...

Try this input:

2 1
1 2
1 2 3

your program gives NO, but must be YES.
The trip is: 1 - 2 - 1 - 2

Why RTE???? Where is Error? I tried to increase array size - but it didn't help #include <cstdio> #include <string> #include <algorithm> using namespace std; int tests,i,n; string s[100]; int len,res; int common(int i, int j) { int k; for(k=0;k<s .size(),k<s[j].size();k++) if (s [k] != s[j][k]) brea...

Thank you very much for algorithm! But soon TLE!!!! How I tired of it!!!! How to speed up it????????????????????????????? #include <cstdio> #include <string> #include <memory> #define MAXLENGTH 1001 using namespace std; class BigInteger{ private: int m[MAXLENGTH]; int len; public: BigInteger(int n) ...

Why number 20 is used here? What does this number mean?

Tell please the algorithm.
Your link does not tell the exact algorithm.
Thanks.

Thank you. But now I have Run Time Error. I don't know why. I corrected my sqrt function - previous program didn't count sqrt(1) Now I have tested a lot - and all seems fine. What about dimention of array? The problem statement says 1000 is enough. Is it so? I tried to put MAXLENGTH = 10001 and get ...

Why Complie Error? Can I use classes on UVA? #include <cstdio> #include <string> #include <memory> #define MAXLENGTH 1001 using namespace std; class BigInteger{ private: int m[MAXLENGTH]; int len; int max(int i, int j) { return (i > j) ? i : j; } public: BigInteger(int n=0) { memset(m,0,sizeof(m)); ...

You are wrong on this test (presented here earlier):

3 3
1 3
1 2 10.0 10.0
1 2 11.0 9.0
2 3 11.0 10.0

Your answer is
1 2 3
20.0 11.0


The correct is

1 2 3
19.0 11.0

Try this test:
aa

This is a palindrome, but your program says that no.
