can someone please point out to me whats wrong with code .
lens = int(input())
arrs = [int(x) for x in input().split()]
petu,ketu = 0, 0
while len(arrs) > 0:
petu += arrs.pop(0)
if len(arrs)>0:
ketu += arrs.pop()
print(abs(petu - ketu))
What I had done is
While there is a value petu point is incrementred with pop(0),if still there is something ketu’s point is incremented with pop.
This process continues till array is empty.
Abs value of petu - ketu should be the answer.
But this is failing on some cases and i would like to know why
