    Can anybody Suggest what is the mistake in my code I belive the logic is correct :

    def subarray(A):
    start = next(x for x, val in enumerate(A) if val > 0) 
    end = next(n-x for x, val in enumerate(A[n:0:-1]) 
                                  if val > 0 )            
    largestValue(Arr=A[start:end])    
def largestValue(Arr):         
    Sum=sum(Arr)
    result=0    
    #print(Arr,l)
    for i in range(len(Arr)-1):
        Sum-=Arr[i]
        result+=Arr[i] * (Sum)       
    print(result)    
n = int(input())

A = list(map(int, input().rstrip().split()))
subarray(A)
