/* 
    Pattern Numbers & Stars - 1

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

    Input Format:    Enter value of N

    Output Format:   All numbers and stars are Space separated

    Sample Input:   5
    
    Sample Output:  1 2 3 4 5
                    1 2 3 4 * 
                    1 2 3 * * *
                    1 2 * * * * *
                    1 * * * * * * *

    Explanation:    Catch the pattern for the corresponding input and print them accordingly.
