It seems easy.. but i can't get it AC. What's the trick?
In the test case, will there be something like:
if so, what is the output?

thank you

The output for your input is:

asdma ... asdaskdj............
qwe.......qweqe .............

Good luck!

so we only have to care about the _last_ 3 dots, is it right?

As the problem statement says:

[quote]The second line will be a string of lowercase characters or blanks ending with three dots

Hei can anybody help me with this problem? i getting wrong answer with this problem all the time. Can anybody give any typical data to test: Here is my program:

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
main()
{
char a[150],b[150],c[150],d[150];
char e[150],f[150],*st;
int i,j,k,n,l;
gets(a);
n=atoi(a);
for(l=0;l<n;l++)
{
gets(a);gets(b);
for(i=0;i<strlen(a);i++)
if(a[i]=='<')
{
for(j=i+1;j<strlen(a);j++)
if(a[j]=='>')
{
for(k=i+1;k<j;k++)
c[k-i-1]=a[k];
c[k-i-1]=0;
break;
}
for(k=j+1;k<strlen(a) && a[k]!=' ';k++)
e[k-j-1]=a[k];
e[k-j-1]=0;
break;
}
for(i=j+1;i<strlen(a);i++)
if(a[i]=='<')
{
for(j=i+1;j<strlen(a);j++)
if(a[j]=='>')
{
for(k=i+1;k<j;k++)
d[k-i-1]=a[k];
d[k-i-1]=0;
break;
}
for(k=j+1;k<strlen(a)&&a[k]!=' ';k++)
f[k-j-1]=a[k];
f[k-j-1]=0;
break;
}
for(i=0;i<strlen(a);i++)
if(a[i]!='<'&& a[i]!='>')
printf("%c",a[i]);
printf("\n");
st=strstr(b,"...");
for(i=0;&b[i]!=st;i++)
printf("%c",b[i]);
printf("%s%s %s%s\n",d,e,c,f);
}
return 0;
}

I think that some judge's input data have one or two sequential dots.

So we must consider these dots ( one or two dots ) as a string.

When I tried to solve this problem in my first time, I checked only whether

a dot appeared or not. But I got WA. So I fixed my code to check three

sequential dots. At last, I got AC. I hope that my experience help your

problem solving. Good Luck~

you have to replace ONLY LAST THREE DOTS ..... in input data is probably test with more then one group of three dots or more than three dots in line ... btw this problem is very easy )

Can anybody please help me... I have tried out quite a few test cases... and even with 1, 2 or more than 3 sequential dots.. which shud be treated as a string....
My prog is giving me correct output for all MY test input, but everytime it is WA.....
does anybody have any idea as to what the judge's test data might be containing which could be tripping my code ?

gvs

here is my code i get RE . y ????

Increase the size of arrays s1,s2,s0,s4, at least to 101.

i changed it to
still RE..........

Using scanf() and gets() at the same time is risky.
Instead of write

thank you so much....... i got AC .. but plz tell me why it is risky to use gets() and scanf() together....... and also y i got RE ?????

scanf() reads upto whitespace like new line and discards it whereas gets() stores the whitespace. So when you use scanf a whitespace is actually left in the buffer and immediate call to gets() causes this whitespace to be stored that is a blank line. That is why you were getting RE, trying to read from a blank string!
Writing this way also might have solved your problem

My code is:



#include <stdio.h>
#include <string.h>




void main()
{
char s1[110] , s2[110] , s3[110] , s4[110] , s5[110] , c1[200] , c2[200] , l2[200] , ch , temp[2] ;

long i , totalpair = 0 ;

scanf("%ld" , &totalpair);

for( i = 0 ; i < totalpair ; i++ )
{


strcpy(s1 , "\0");
strcpy(s2 , "\0");
strcpy(s3 , "\0");
strcpy(s4 , "\0");
strcpy(s5 , "\0");
strcpy(c1 , "\0");
strcpy(c2 , "\0");
strcpy(l2 , "\0");

fflush(stdin);


while( (ch = getchar() ) != '<' )
{
temp[0] = ch;
temp[1] = '\0';

strcat(s1 , temp);
}

while( (ch = getchar() ) != '>' )
{
temp[0] = ch;
temp[1] = '\0';

strcat(s2 , temp);
}

while( (ch = getchar() ) != '<' )
{
temp[0] = ch;
temp[1] = '\0';

strcat(s3 , temp);
}

while( (ch = getchar() ) != '>' )
{
temp[0] = ch;
temp[1] = '\0';

strcat(s4 , temp);
}

while( (ch = getchar() ) != '\n' )
{
temp[0] = ch;
temp[1] = '\0';

strcat(s5 , temp);
}



strcpy(c1 , s1);
strcat(c1 , s2);
strcat(c1 , s3);
strcat(c1 , s4);
strcat(c1 , s5);



while( (ch = getchar() ) != '.' )
{
temp[0] = ch;
temp[1] = '\0';

strcat(l2 , temp);
}


while( (ch = getchar() ) != '\n') {}


fflush(stdin);



strcpy(c2 , l2);
strcat(c2 , s4);
strcat(c2 , s3);
strcat(c2 , s2);
strcat(c2 , s5);



printf("%s\n",c1);
printf("%s\n",c2);




}

}





It is giving PE.
Can anyone help me?
Please.
