#                 10-row School abacus
#
#########################################################################
#       Description partially extracted from from wikipedia
#
#  Around the world, abaci have been used in pre-schools and elementary
#
# In Western countries, a bead frame similar to the Russian abacus but
# with straight wires and a vertical frame has been common (see image).
# Helps schools as an aid in teaching the numeral system and arithmetic
#
#         |00000*****   |     row factor 1000000000
#         |00000*****   |     row factor 100000000
#         |00000*****   |     row factor 10000000
#         |00000*****   |     row factor 1000000
#         |00000*****   |     row factor 100000
#         |00000*****   |     row factor 10000
#         |00000*****   |     row factor 1000
#         |00000****   *|     row factor 100     * 1
#         |00000***   **|     row factor 10      * 2
#         |00000**   ***|     row factor 1       * 3
#                                        -----------
#                             Sum                123
#
# Each row represents a different row factor, starting with x1 at the
# bottom, ascending up to x1000000000 at the top row.

# The procedure print_abacus(integer) takes a positive integer
# and prints a visual representation (image) of an abacus setup for a
# given positive integer value.

#SOLUTION ONE
#def print_abacus(value):
#    lo = []
#    if value == 0:
#        print('|00000*****   |\n'*10)
#    else:
#        g = len(str(value))
#        while value >= 1:
#            p = '|00000*****|'
#            i = 11
#            k = value%10
#            lo.append(p[:i-k]+" "*3+p[i-k:])
#            value = value / 10
#        print('|00000*****   |\n'*(10-g)),
#        while g > 0:
#            print lo.pop()
#            g-=1


#SOLUTION TWO
