'''
vector = [0, 1, 0, 2, 1, 0, 1, 3, 2, 1, 2, 1]

total_water = 0
scan_lines = max(vector)

for current_level in range(0, scan_lines):
for i in range(0, len(vector)):
if vector[i] > current_level:
start_l = i
break
for i in range(len(vector)-1, -1, -1):
if vector[i] > current_level:
end_l = i
break
for i in range(start_l, end_l+1):
if vector[i] < current_level + 1:
total_water = total_water + 1

print(total_water)
'''

in console I get 6 like expected however saying that output is 2!

Is it some bug?
