Matrix – Column-wise Decrement: Given an integer N then form an N*N matrix by assigning the value N as starting value and incrementing each successive cell value by N for the first row and from the second row decrement the values column-wise by the column number. Then the program must print the matrix.

Boundary Condition(s):
1 <= N <= 100

Input Format:
The first line contains N.

Output Format:
Matrix Pattern.

Example Input/Output 1:

Input:
3

Output:
3 6 9
2 4 6
1 2 3

Example Input/Output 2:

Input:
4

Output:
4 8 12 16
3 6 9 12
2 4 6 8
1 2 3 4

Python:

a=int(input())
for i in range(a,0,-1):
   for j in range(1,a+1):
       print(i*j,end=' ')
   print()

n=int(input())
for i in range(n,0,-1):
    k=i
    for j in range(n,0,-1):
        print(k,end=" ")
        k+=i
    print()

C:

#include<stdio.h>
#include <stdlib.h>
int main()
{
    int n;
    scanf("%d",&n);
    int store=n;
    for(int i=0;i<n;i++){
        for(int j=0;j<n;j++){
            printf("%d ",(j+1)*store);
        }
        store--;
        printf("n");
    }
}
