I have the same problem here...
can any body give me another sample I/O ?
just feeling depressed from getting 6 WAs in a row , after 2 years idle from UVA

Every person exists for another person. and that person exists for the other one. it's just the matter of existence...

Anybody Help PLZ about 10192
I am also getting WA for this problem, but i think my algo and code is OK.
I also checked my code for some I/O. It gives me correct output.
Then wheres the worng.
Here my code:

10192 WA help!
I think my algorithm is correct but get WA! I check many times but cant find where the problem is. I will be very grateful if any suggestion.
Code: Select all
#include <cstdlib>
#include <stdio.h>
#include <iostream>
#include <string>
#define MAXCITY 102
using namespace std;
int c[MAXCITY][MAXCITY];
char s1[MAXCITY], s2[MAXCITY];
void LCS(int time){
int m = strlen(s1);
int n = strlen(s2);
int i, j;
for(i=0; i<MAXCITY; i++)
for(j=0; j<MAXCITY; j++)
c[i][j] = 0;
for(i=0; i<m; i++){
for(j=0; j<n; j++){
if(s1[i] == s2[j]) c[i][j] = c[i1][j1]+1;
else c[i][j] = (c[i][j1]>c[i1][j])? c[i][j1] : c[i1][j];
}
}
cout << "Case #" << time << " : you can visit at most " << c[m1][n1] << " cities." << endl;
}
int main(int argc, char *argv[])
{
int time;
for(time=1; ; time++){
gets(s1);
if(!(strcmp(s1, "#"))) return 0;
gets(s2);
LCS(time);
}
return EXIT_SUCCESS;
}

I was solve this problem with Dynamic Algorithm

Sorry, I've looked at the old topics for this problem and read the code in those topics but I still don't understand why my code repeatedly gets me WA. I'm just using the standard LCS algorithm. Could someone please help me?
Thanks in advance.
Code: Select all
#include <stdio.h>
#include <string.h>
#define SIZE 110
#define MAX(a, b) (a > b ? a : b)
static long best[SIZE][SIZE];
static char line1[SIZE], line2[SIZE];
static int len1, len2;
static int i, j;
static int num;
int main (){
gets (line1);
num = 0;
while (strcmp (line1, "#") != 0){
gets (line2);
num++;
len1 = strlen (line1);
len2 = strlen (line2);
for (i = 0; i < len1 + 1; i++)
best[i][0] = 0;
for (j = 0; j < len2 + 1; j++)
best[0][j] = 0;
for (i = 1; i < len1 + 1; i++)
for (j = 1; j < len2 + 1; j++)
if (line1[i] == line2[j])
best[i][j] = best[i  1][j  1] + 1;
else
best[i][j] = MAX(best[i  1][j], best[i][j  1]);
printf ("Case #%d: you can visit at most %ld cities.\n", num, best[len1][len2]);
gets (line1);
}
return 0;
}
