            for i in range(a+2):
                if j != a:
                    if i == 0 or i == a+1:
                        print('*',end="")
                    else:
                        print(' ',end="")
                else:
                    print('*',end="")
            if j != a:
                print('\n',end="")
            else:
                print('\n')
       
    except:
        break
