Input Formate:

  Integer, List

Output Formate:

 Integer, Integer

Input:    

3
 1 2 3
4 5 6

 7 8 9

Output:

15
15

--Solution-- 

  def DiagCalc(M): s1=0 s2=0 for i in range(len(M)): for j in range(len(M)): if i==j: s1+=M[i][j] if i+j==len(M)-1: s2+=M[i][j] print(s1) print(s2,end='') M=[] n=int(input()) for i in range(n): M.append([int(i) for i in input().split()]) DiagCalc(M)

Input Formate:

  Integer, List(Matrix)

Output Formate:

 Transpose Matrix


Input

  2
  1   2
 3  4

Output

  1  3
  2 4

--Solution-- 

  def Transpose(M): a=[] for i in range(len(M[0])): b=[] for j in range(len(M)): b.append(M[j][i]) a.append(b) return a

   n = int(input())
   M = []
   for i in range(n):

         L = list(map(int, input().split()))
         M.append(L) 

   print(Transpose(M))

Given a matrix M write a function snake that accepts a matrix M and returns a list which contain elements in snake pattern of matrix M.

Input Formate:

 Integer, List(Matrix)

Output Formate:

 Snake List

Input

 2
 1  2
3  4

Output
 [1,  2,  4,  3]

--Solution-- 

  def snake(M): a=[] for i in range(len(M)): if i%2==0: a+=M[i] else: a+=M[i][::-1] return a

n = int(input())
M = []
for i in range(n):
    L = list(map(int, input().split()))
    M.append(L)
print(snake(M))
