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 ) wh...

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(in...
