Programming Assignment 1

Question 1 : Given a sqaure matrix M, write a function DiagCalc which calculate the sum of left and right diagonals and print it respectively.

Input : A matrix M 
            [[1,2,3],[3,4,5],[6,7,8]] 

Output : 13

               13

				
					def DiagCalc(M):
        n = len(M)
        left_diagonal_sum = 0
        right_diagonal_sum = 0
        
        for i in range(n):
            left_diagonal_sum += M[i][i]
            right_diagonal_sum += M[i][n - 1 - i]
        
        print(left_diagonal_sum)
        print(right_diagonal_sum,end="")
        
n = int(input())
M = []
for i in range(n):
    L = list(map(int, input().split()))
    M.append(L)

DiagCalc(M)

Programming Assignment 2

Question 2 : Given a matrix M write a function Transpose which accepts a matrix M and return the transpose of M.
Transpose of a matrix is a matrix in which each row is changed to a column or vice versa.

Input : A matrix M
            [[1,2,3],[4,5,6],[7,8,9]]

Output : Transpose of M
               [[1,4,7],[2,5,8],[3,6,9]]

				
					def Transpose(M):
    rows, cols = len(M), len(M[0])
    transposed = [[0 for _ in range(rows)] for _ in range(cols)]

    for i in range(rows):
        for j in range(cols):
            transposed[j][i] = M[i][j]
    return transposed

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

Programming Assignment 3

Question 3 : 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 : A matrix M

      91 59 21 63 
      81 39 56 8 
      28 43 61 58 
      51 82 45 57

Output : [91, 59, 21, 63, 8, 56, 39, 81, 28, 43, 61, 58, 51, 82, 45, 57]

				
					def snake(matrix):
        snake_pattern = []
        rows, cols = len(matrix), len(matrix[0])
    
        for i in range(rows):
            if i % 2 == 0:
                for j in range(cols):
                    snake_pattern.append(matrix[i][j])
            else:
                for j in range(cols - 1, -1, -1):
                    snake_pattern.append(matrix[i][j])
    
        return snake_pattern
        
n = int(input())
M = []
for i in range(n):
    L = list(map(int, input().split()))
    M.append(L)

print(snake(M))
