/* 
    Pattern Numbers & Stars - 2

    Take as input N, a number. Print the pattern as given in the input and output section.

    Input Format:   Enter value of N

    Constraints:    1 <= N < 10

    Output Format:  Print the pattern.

    Sample Input:   7

    Sample Output:  1******
                    12*****
                    123****
                    1234***
                    12345**
                    123456*
                    1234567

    Explanation:    There is no space between any two numbers. Catch the pattern for corresponding input and print them accordingly.
