even after so many days passed still strugging with PERCAPTA

i tried posting my query in many threads of codechef but nothing happened .

the only reason is my language (python)

i would be greatefull if u any of u guys helps me…

thanks…

below is my code which works for sample inputs and random test cases i tried . gives RE neither TLE nor WA

```
import collections
def dfs(p):
visited.add(p)
temp.add(p+1)
for node in road[p]:
if(node not in visited and selected[node]):
dfs(node)
t=int(input())
for _ in range(t):
n,m=map(int,input().split())
income=list(map(int,input().split()))
pop=list(map(int,input().split()))
road=collections.defaultdict(list)
for __ in range(m):
a,b=map(int,input().split())
road[a-1].append(b-1)
road[b-1].append(a-1)
i=income[0]
p=pop[0]
# to find max per capita
for x in range(1,n):
if(i*pop[x]<p*income[x]):
i=income[x]
p=pop[x]
selected=[False]*n
# to select node with max per capita
for x in range(n):
if(pop[x]*i== income[x]*p):
selected[x]=True
visited=set()
ans=set()
for each in range(n):
if(each not in visited and selected[each]):
temp=set()
dfs(each)
if(len(temp)>len(ans)):
ans=temp
print(len(ans))
print(*ans)
```
