def answer(s):
# readme.txt
if(len(s) > 100 or len(s) < 1):
raise ValueError('Height is outside of bounds')
# we keep only the arrows and cast it into a list ot make it iterable easily
s = list(s.replace("-",""))
left = []
right = []
for i in range(0,len(s)):
if s[i] == '<':
if s[i] == '>':
# two nested loops to detect collision
for i in right:
for y in left:
if i < y:
for i in left:
for y in right:
if y < i:
return res
