for i in range(1,int(raw_input())+1): #More than 2 lines will result in 0 score. Do not leave a blank line also
    print sum(map(sum, map(lambda y: map(lambda x: 10 ** x, xrange(y)), xrange(1, i + 1)))) * (10 ** (i-1))+sum(map(sum, map(lambda y: map(lambda x: 10 ** (i - x - 2), xrange(y)), xrange(1, i))))
