I solved this problem using Dijkstra and Differentiation.....

After a quick overview i found a bug to your problem. you take the input N and R and instead of taking R roads you are taking N roads of information.

However if you correct this i think you will get tle.......
In the warshall() function u used a loop
for( double x = 0.00; x <= v[z][l]; x += eps ...

Any idea how to solve this problem??
Thanks in advance.

hi nayimsust, i checked your code.just use memset or initialize ur mat[][] variable before your while loop and u will be ok.
And try to do simple codes.

hi everyone,i am getting run time error a lot in this prob.
could anyone check my code to tell the cause of wa.
//code here
#include<stdio.h>
#include<stdlib.h>
#define inf 100000

int fire[1005][1005],min;
char input[1005][1005];
int row,col,que[1000005][3],r[]={0,0,-1,1},c[]={-1,1,0,0};

void BFS ...

hi everyone, i m getting wa in this problem many times.can anyone give me some critical input outputs.Thnx in advance.

hi,could anyone give some input,for that my prog goes wrong.Thnx in advance.

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

int main()
{
int n,i,j,total,used[30][30],flag,num=1,max,len;
char input[30][30];

while(scanf("%d",&n)==1)
{
for(i=0,max=0;i<n;i++)
{
scanf("%s",input );
len=strlen(input ...

i m getting wa wa wa!
could anyone check and tell my errors.
here is my code-

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

int main()
{
int value[258],ascii[258],frq[130],i,j,k,tmp,start=0,len;
char input[1000];

while(gets(input)!=NULL)
{


if(start)
printf("\n");
start=1 ...

hi MRH thanks for ur help.

hi,i m getting wa in this input.i dont understand my fault.could anybody check my prog.

#include<stdio.h>

int main()
{
int a[13],n,total[14],k=1,i;
bool flag[13];

while(scanf("%d",&n)==1)
{
if(n<0)
break;

total[1]=n;
for(i=1;i<13;i++)
{
scanf("%d",&a );
total[i+1]=total +a ;
flag ...
