Code not working

#1

The code is giving segmentation fault
code-https://ide.codingblocks.com/s/341563

#2

vector dis(100005,0);
this is correct way to declare vector of size N with intial val 0

also you have to set visited to 0 every time

#3

I did the necessary changes but the code still isn’t getting submitted. code-https://ide.codingblocks.com/s/341563

there are few more mistakes in your code

  1. at line no 26 to 33
if (vis[x] == 0)
            {
                // dis[x]=dis[src]+1;
                dis[x] = dis[node] + 1;
                // also you have to mark x as visited
                vis[x] = 1;
                q.push(x);
            }
  1. also in main()
    while print the ans you have to run loop from i=1 to i<=n
    this is because p can be 1 or not 1
    so handle accordingly

i have done all these changes in modifed Code attached below
you can see and if you have any doubt feel free to ask
