1.合数就分解，质数输出本身。
import math def fenjie(n): res=[] u=math.sqrt(n) for i in range(2,int(u)+1): while n%i==0: res.append(i) n=n/i if n!=1: res.append(n) print(res) fenjie(12)
2.给出一个包含字母的二维表格和一个单词，判断能否从表格某位置出发，得到该单词。
biaoge = []
while 1:
s = input()
if ',' in s:
biaoge.append(s.split(','))
else:
break
word = s
def dongzuo(i,j,word,visited):
if not word:
return True
if 0<=i<len(biaoge) and 0<=j<len(biaoge[0]) and biaoge[i][j]==word[0] and visited[i][j]==0:
visited[i][j]=1
return dongzuo(i-1,j,word[1:],visited) or dongzuo(i+1,j,word[1:],visited) or dongzuo(i,j+1,word[1:],visited) or dongzuo(i,j-1,word[1:],visited)
else:
return False
def run():
for i in range(len(biaoge)):
for j in range(len(biaoge[0])):
visited = [[0 for _ in range(len(biaoge[0]))]for _ in range(len(biaoge))]
if dongzuo(i,j,word,visited):
print('true')
return
print('fasle')
run()
