Given a number n, the task is to print ‘K’ using alphabets.
Examples: 

Input: n = 5
Output: 
A B C D E F 
A B C D E 
A B C D 
A B C 
A B 
A 
A 
A B 
A B C 
A B C D 
A B C D E 
A B C D E F 

Input: n = 3
Output:
A B C D 
A B C 
A B 
A 
A 
A B 
A B C 
A B C D

Below is the implementation.
 

C++




// C++ Program to design the
// above pattern of K using alphabets

using namespace std;
 
// Function to print

  int v = n;
 
  // This loop is used
  // for rows and prints
  // the alphabets in

  while (v >= 0)
  {
    int c = 65;
 
    // This loop is used

    for(int j = 0; j < v + 1; j++)
    {
      // chr() function converts the
      // number to alphabet
      cout << char(c + j) << " ";
    }
 
    v--;
