蛇形矩阵 用dp函数来解答

解题思路:

注意事项:

参考代码:

n=nt(input())
dp=[[0]*n for i in rage(n)]
dp[0][0]=1
for i in range(1,n):
   dp[i][0]=dp[i-1][0]+i
for i in range(n):
   k=i+1
   for j in range(1,n-i):
       dp[i][j]=dp[i][j-1]+j+k
t=n+1
for i in dp:
   t-=1
   p=i[:t:]
   ss=[str(z) for z in p]
   s=' '.join(ss)
   print(s)
