1.

字符串逆序

import sys

'''
waimai,dache,lvyou,liren,meishi,jiehun,lvyoujingdian,jiaopei,menpiao,jiudian
'''

s=sys.stdin.readline().strip().split(",")

if len(s)==0:
    print ""
elif len(s)==1:
    print s[0]
else:
    res=[]

    for i in range(len(s)-1):
        for j in range(i+1,len(s)):
            if s[i] in s[j] :
                continue
            elif s[j] in s[i]:
                tmp = s[i]
                s[i] = s[j]
                s[j] = tmp
                continue
            if s[i]

2.最长公共前缀，AC了。

import sys

n=int(sys.stdin.readline().strip())

ss=[]
for i in range(n):
    ss.append(sys.stdin.readline().strip())

while True:
    a,b=map(int,sys.stdin.readline().strip().split(" "))
    a=a-1
    b=b-1

    if ss[a]==[] or ss[b]==[]:
        print 0
        break

    count=0
    i,j=0,0
    while i
