Issue with code

#1

What’s wrong with my code ?

#2 
n=int(input())
li=[int(ele) for ele in input().strip().split()]
left=0
right=n-1
area=0
while left<=right:
  area=max(area,min(li[left],li[right])*(right-left))
  if li[left]<li[right]:
    left+=1
  else:
    right-=1
print(area)

hello @ritvikagrawal1 your logic is not correct.
dry run for this test case:
6
3 0 0 2 0 4
correct ouput is 10.
the logic is you have to create 2 list storing the maximum from left to right and the maximum frim right to left.
like in the above example.
maximum from left to right is:3 3 3 3 3 4
maximum from right to left is:4 4 4 4 4 4
you haveto min(from both the arrays and stort at the corresponding index)
like:
3 3 3 3 3 4
and subtract the corresponding element from the oroginal list which youhave in input.
so the final array will be
0 3 3 1 3 0
and then you have to take the sum of all these estimations.
that will be 10.
try to frame your logic in this way.
