Write a python program, that will be able to determine whether a number is divisible by 3 by adding all of its digits. Limitation: 1. Do not use string manipulation. 2. Use only basic arithmetic operators and control structures. 3. Treat the number as an integer only. Example Enter number: 4567090921810 Divisible by 3 Process Demo 4567090921812 4+5+6+7+0+9+0+9+2+1+8+1+2 - 54 514-9 When the number became a single digit, check if it is 3, 6 or 9. If it is, the number is divisible by 3
