Your codes are giving wrong answer for

5 3

1 2

2 3

4 5

-1

-1

-1

1

1

correct answer is -1 but your answer is 2.

```
for(int i=1;i<=n;i++)
{dfs(i);}
for(int i=1;i<=n;i++)
{co[i]=mi;visited[i]=0;}
```

I think this is wrong. mi will be 1 and it will assign all co[i] to 1 thats why your answer is 2.
