Question

5. (10 points) Write a function that takes a square matrix and compute the summation of items on both diagonals. Example: 9 13 5 27 1 11X76 6 0 7 102

Write the code in python

Answer 1

Answer: here is the answer for your code:

code:

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------

def Sum_Of_Diagonal (a,dim):
#variables to store sum of diagonals and initialized to 0
Sum_Of_Diagonal1 = 0
Sum_Of_Diagonal2 = 0
for rows in range(0, dim):
for columns in range(0, dim):
if (rows == columns):# condition for Diagonal1

Sum_Of_Diagonal1 = Sum_Of_Diagonal1+a[rows][columns]

if ((rows + columns) == (dim - 1)):# condtion for Diagonal2
Sum_Of_Diagonal2 = Sum_Of_Diagonal1+a[rows][columns]
  
  
print ("sum of 1st Diagonal:", Sum_Of_Diagonal1)
print ("sum of 2nd Diagonal:",Sum_Of_Diagonal2)

a =[[9, 13, 5, 2],
[1, 11, 7, 6],
[3, 7, 4, 1],
[6,0, 7, 10]]

Sum_Of_Diagonal (a,4)#calling function

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------

OUTPUT:

main.py 1. def Sum_Of_Diagonal (a, dim): #variables to store sum of diagonals and initialized to @ 3 Sum_Of_Diagonal1 = 0 4 Sum_Of_Diagonal2 = 0 5 for rows in range(0, dim): for columns in range(@, dim): if (rows == columns) :# condition for Diagonali, Sum_Of_Diagonal1 = Sum_of_Diagonal1+a[rows][columns] if ((rows + columns) == (dim - 1)):# condtion for Diagonal 2 Sum_Of_Diagonal2 = Sum_Of_Diagonal1+a[rows][columns] print ("sum of 1st Diagonal:", Sum_Of_Diagonali) print ("sum of 2nd Diagonal:",Sum Of Diagonal2) 19 20 21 22 a =[[9, 13, 5, 2], [1, 11, 7, 6), [3, 7, 4, 1], [6,0, 7, 10]] 23 24 Sum_Of_Diagonal (a, 4)#calling function input sum of 1st Diagonal: 34 sum of 2nd Diagonal: 30 ... Program finished with exit code o Press ENTER to exit console.
