PATTERN1 - Simple Pattern !!

no tags 

Today Yogesh learned about the loops and its application in his programming classes. One application which the professor told was about printing the patterns, the pattern which Yogesh learned was

                            1
                            123
                            12345
                            1234567

Yogesh is given an assignment to print a pattern using letters (capital only) up to n lines of following format
                            
                            ABCD
                            BCD
                            CD
                            D

Now Yogesh is unable to find the solution. So he has come to you, as you are his good friend you have to help him.
