CCXXXI_

从统计数据来看,这堆东西跑起来竟然能比多数cpp答案快,奇妙

p, l = map(int, input().split())
if l == 1:
    print(input())
    exit()
d, e = dict(), set()
for i in range(p):
    t = [input() for j in range(l)]
    d[t[0]] = t
    e.add(t[-1])
h = (set(d) - e).pop()
print(d[h][0])
while h in d:
    t = d[h]
    print(*t[1:], sep='\n')
    h = t[-1]
