蛇行矩阵题解

解题思路:

注意事项:

参考代码:'''
思路:
先求出第一行
后面就是a[i][j] = a[i-1][j+1]-1
'''
def dyh(n):
   a = [0]*n
   h=0
   for i in range(n):
       h+=i+1
       a[i] = h
   return a

n = int(input())
a = dyh(n)
b = [0]*n
b[0] = a
c = [0]*(n-1)
for i in range(1,n):
   for j in range(n-i):

       c[j] = a[j+1]-1

   a = c
   b[i] = c
   c = [0]*(n-i-1)


for i in range(n):
   c = b[i]
   for j in range(len(c)):
       print(c[j],end=' ')
   print()
