My issue

I am new to coding and codechef, this is the first problem where there are subtasks. I have done coding for subtask with original constraints. I don’t know where to submit the coding for first subtask.

My code

# cook your dish here
N=int(input())
C=list(map(int, input(). split()))
T=list(map(int, input(). split()))
min_1=[]
min_2=[]
min_3=[]
for i in range(N):
    if T[i]==3:
        min_3.append(C[i])
    elif T[i]==1:
        min_1.append(C[i])
    else:
        min_2.append(C[i])
        
#print(min_1, min_2,min_3)
#print((min(min_1)),(min(min_2)),(min(min_3)))
trans=min(min_1)
author=min(min_2)
trans_author=min(min_3)
if trans+author>=trans_author:
    print(trans_author)
else:
    print(trans+author)
