Program to find sum of elements in each row and each column of the given matrix and print the greatest of the same

Published on 10 Mar 2020

Program to find the sum of elements in each row and each column of the given matrix and print the greatest of the same is discussed here. Input the matrix and find the sum of each row and each column and display the row having the greatest sum and also the column having the greatest sum.


For example, consider the matrix

mat = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}

Sum of row 1 = 1 + 2 + 3 = 6

Sum of row 2 = 4 + 5 + 6 = 15

Sum of row 3 = 7 + 8 + 9 = 24


Row 3 is having the greatest sum.


Sum of column 1 = 1 + 4 + 7 = 12

Sum of column 2 = 2 + 5 + 8 = 15

Sum of column 3 = 3 + 6 + 9 = 18


Column 3 is having the greatest sum.


Algorithm to find the sum of elements in each row and each column of the given matrix


  • Input the number of rows and columns of the matrix.
  • Input the matrix elements.
  • Traverse the matrix and find the sum of each row and each column and display them.
  • Find the row having the greatest sum and display it.
  • Find the column having the greatest sum and display it.


Program to find the sum of elements in each row and each column of the given matrix and print the greatest of the same

Python 3

Output
Enter the order of the matrix : 3 3
Input the matrix elements :
1 2 3
4 5 6
7 8 9
Sum of rows is 6 15 24
Row 3 has maximum sum
Sum of columns is 12 15 18
Column 3 has maximum sum
