# Print a Star Pattern in Python without using loop
import math

# It's the recursive function
# to print the star pattern
def starPattern(n = 0, i = 1, r = 1):
    print (end="*") if (int (math.sqrt(math.pow((i - (2 * n - 1) *(r - 1) - n), 2))) < r) else print (end=" ")

    if ((i - (2 * n - 1) * (r - 1)) % (2 * n - 1) == 0):
        print (end="\n")
        r += 1

    if (i < n * (2 * n - 1)):
        i += 1
        starPattern(n, i, r)


# It's the driver code for computing
print ("-----Enter the size of the pattern-----")

# size of the pattern
x = int (input ())

# This will print the pattern
starPattern(x)
