Given a 2D integer array of size M*N, find and print the sum of ith column elements separated by space.

Column Wise Sum

Given a 2D integer array of size M*N, find and print the sum of ith column elements separated by space.

Input Format :

First and only line of input contains M and N, followed by M * N space separated integers representing the elements in the 2D array.

Output Format :

Sum of every ith column elements (separated by space)

Constraints :

1 <= M, N <= 10^3

Sample Input :

4 2 1 2 3 4 5 6 7 8

Sample Output :

16 20

SOURCE CODE : 

#include<iostream>

using namespace std;

int main(){

    int m,n;

    cin>>m>>n;

    int input[m][n];

for(int i = 0;i<m;i++)

 {

     for(int j = 0;j<n;j++)

     {

         cin>>input[i][j];

     }

 }

  for(int col = 0;col<n;col++)

  {

      int sum = 0;

      for(int row= 0;row<m;row++)

      {

          sum = sum + input[row][col];

      }

      cout<<sum<<" ";

  }
