The Joy of Computing Using Python

Week 7 Programming Assignment 1

Last Day of Submission: 15-Sep-2022

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

Input Formate:

  Square Matrix

Output Formate:

 Two Number(sum of both diagonals)

Input:
[[1, 2],[3, 4]]

Output:

5

5

--Solution-- 

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

Week 7 Programming Assignment 2

Last Day of Submission: 15-Sep-2022

Given a matrix M of MxN write a function Transpose which accepts a matrix M and return the transpose of M.

Input Formate:

  Matrix

Output Formate:

 Transposed Matrix


Input
[[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))'''

Week 7 Programming Assignment 3

Last Day of Submission: 15-Sep-2022

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

Input Formate:

  Matrix

Output Formate:

 List

Input

 [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

Output
 [[1, 2, 3], [6, 5, 4], [7, 8, 9]]

--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))'''
