Question

Mathematical functions map naturally to program functions and modules often are used to group such functions for reuse In the Bukiyip language, coconuts, days and fish are counted in base 3. Numbers use only the digits 0-2, such that instead of "tens" and "hundreds", the second and third digits represents multiples of 3 and 9 respectively Reference: http://mentalfloss.com/article/31879/12-mind-blowing-number-systems-other- languages) Write a Python module called 'bukiyip.py' with the following functions for simple Bukiyip arithmetic, assuming that all values have at most 3 digits bukiyip_to_decimal (a) Convert a Bukiyip number to decimal decimal_to_bukiyip(a) Convert a decimal number to Bukiyip bukiyip add (a, b) Add two Bukiyip numbers. buk?yip, multiply (a, Multiply two Bukiyip numbers . b) A main program has been supplied as 'bu kiyipmodtest. py'-use this to test your program and do not change this file Sample /o Bukiyip test program Available commands: d convert given decimal number to base-3. b convert given base-3 number to decimal.

====outpu====================

Available commands:

d <number> : convert given decimal number to base-3.

b <number> : convert given base-3 number to decimal.

a <number> <number> : add the given base-3 numbers.

m <number> <number> : multiply the given base-3 numbers.

q : quit

Enter a command:d 12
110
Enter a command:b 20
6
Enter a command:a 12 11
100
Enter a command:m 12 11
202
Enter a command:q
