Printing a pyramid pattern of digits #9

//This java program accepts a number of user
//which tells the program that how many lines
//of the pattern will be printed and then prints
//the pattern of the given number of lines.
/*Sample Input : 7

Sample Output :
            7
          767
        76567
      7654567
    765434567
  76543234567
7654321234567 */
