We have to print natural numbers columns wise with decreasing size, depending upon given number of lines as described in the examples below.

Examples :

Input : 5
Output :
1
2 6 
3 7 10
4 8 11 13
5 9 12 14 15

Input : 3
Output :
1
2 4
3 5 6

Approach :

  1. We will take the outer for loop, which is for how many lines we want to print.
  2. Since we want to print natural number column by column, for this we will take an inner for loop. In the above example the number of element is depending upon number for i, therefore we take a variable k which is equal to i
Value of i    ||     Number of Element
    1         ||          1
    2         ||          2
    3         ||          3     so on
  1. Using the logic k = k + n – j, we will get natural numbers according to requirement.

C++




// CPP Program to natural numbers columns wise
#include <bits/stdc++.h>
using namespace std;
  
void pattern(int n)
    // Outer loop for how many 
    // lines we want to print
    for (int i = 1; i <= n; i++) {
        int k = i;
  
        // Inner loop for printing
        // natural number
        for (int j = 1; j <= i; j++) {
            cout << k << " ";
  
            // Logic to print natural
            // value column-wise
            k = k + n - j;
        }
        cout << " \n";
    }
}
  
// Driver Code
int main()
{
    // get value from user
    int n = 5;
      
    // function calling
    pattern(n);
      
    return 0;
}

            // Inner loop for printing natural number
            for (int j = 1; j <= i; j++) 
            {
                System.out.print(k);
                  
                // Logic to print natural value column-wise
                k = k + n - j;
            }
            System.out.println();
        }

    // Driver Code
    public static void main(String[] args)

        p.display();
    }
}


Python3




# Python Program to natural numbers columns wise
  
def display():
        n = 5
        i = 1
  
        # Outer loop for how many lines we want to print
        while(i<=n): 
            k = i
            j = 1
  
            # Inner loop for printing natural number
            while(j <= i): 
                print (k,end=" ")
                  
                # Logic to print natural value column-wise
                k = k + n - j
                j = j + 1
                  
            print("\r")
            i = i + 1

Output

1  
2 6  
3 7 10  
4 8 11 13  
5 9 12 14 15  

Time Complexity: O(n2)
Auxiliary Space: O(1)
