# You are given a positive integer N. 
# Your task is to print a palindromic triangle of size N.

# For example, a palindromic triangle of size 5 is:

# 1
# 121
# 12321
# 1234321
# 123454321

# You can't take more than two lines. The first line (a for-statement) is already written for you. 
# You have to complete the code using exactly one print statement.

# Note: 
# Using anything related to strings will give a score of 0. 
# Using more than one for-statement will give a score of 0.

# Input Format
# A single line of input containing the integer N.

# Constraints
# 0 < N < 10

# Output Format
# Print the palindromic triangle of size N as explained above.

# Sample Input
# 5

# Sample Output
# 1
# 121
# 12321
# 1234321
# 123454321
# ------------------------------------------------------------------------------------------------------------------------------------------

for i in range(1,int(input())+1): #More than 2 lines will result in 0 score. Do not leave a blank line also
    print((10**i-1)**2//81)
