Question 1
Given a sqaure matrix M, write a function DiagCalc that calculates the sum of left and right diagonals and prints it respectively.
Input:
A Number M
A Matrix with M rows and M columns
[[1,2,3],[3,4,5],[6,7,8]]
Output
13
13
Explanation:
Sum of left diagonal is 1+4+8 = 13
Sum of right diagonal is 3+4+6 = 13
Solution:
def DiagCalc(M):
countL = 0
countR = 0
for i in range(len(M)):
countL += M[i][i]
countR += M[i][-1 - i]
print(countL)
print(countR)
n = int(input())
M = []
for i in range(n):
L = list(map(int, input().split()))
M.append(L)
DiagCalc(M)These are answers of The Joy of Computing using Python Assignment 7 Answers
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]]
Solution:
def Transpose(M):
rowlen = len(M)
collen = len(M[0])
ans = [[] for i in range(collen)]
for i in range(collen):
for j in range(rowlen):
ans[i].append(M[j][i])
return ansThese are answers of The Joy of Computing using Python Assignment 7 Answers
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. (See explanation to know what is a snake pattern)
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]
Explanation:
For row 1 elements are inserted from left to right
For row 2 elements are inserted from right to left
For row 3 elements are inserted form left to right
and so on
Solution:
def snake(M):
rowlen = len(M)
collen = len(M[0])
ans = []
for i in range(rowlen):
if i%2 == 0:
for j in M[i]:
ans.append(j)
else:
l = M[i]
for j in range(-1, -collen-1, -1):
ans.append(l[j])
return ansThese are answers of The Joy of Computing using Python Assignment 7 Answers
