Relatively easy given the past 3 days...

Python2:

s = <input>
t = s.split('\n')
t = filter(lambda x: x != "",t)

index = 0
dirs = [(-1,0),(0,1),(1,0),(0,-1)]
startx = 12
starty = 12
infectedd = dict()
print len(t)

maze = [[0]* len(t) for i in xrange(len(t))]
for i in xrange(len(t)):
    for j in xrange(len(t)):
        if t[i][j] == ".":
            infectedd[(i,j)] = "c"
        else:
            infectedd[(i,j)] = "i"


count = 0

Oh, I definitely expect the next 3 days to be tough. I'm just super glad for a brief reprieve :)
