## Discussion of Problem 1642. 1D Maze

wrong test 7 input data
Posted by thegriglat 27 Feb 2013 12:52
My python 2.6 code:
============
#!/usr/bin/python
import sys

def getDist(path,pr,pl):
global x
coord = 0
i = 0
if path == 1:
pp = 1
else:
pp = -1
while coord != x:
if pp == 1:
try:
bord = pr.pop(0)
except:
bord = None
else:
try:
bord = pl.pop(0)
except:
bord = None
while coord != bord :
coord +=  pp
i += 1
if coord == x:
break
pp *= -1
return i

(n,x) = (int(x) for x in sys.stdin.readline().rstrip().split(" "))
p = [int(j) for j in sys.stdin.readline().split()]
p.sort()
pr = []
pl = []
for i in xrange(len(p)):
if p[i] >= 0:
pr.append(p[i])
else:
pl.append(p[i])
pl.reverse()
dist = 0
if pr == []:
pr = [1000]
if pl == []:
pl = [-1000]
if x > max(pr) or x < min(pl):
print  "Impossible"
else:
print getDist(1,pr,pl), getDist(-1,pr,pl)
===========

Another test's on forum is OK

What input data on test 7?
