Automate My Lottery System

I want to automate this pick 3 lottery system. The system will have an input and an output. The user will enter, the last number drawn in their state pick 3 game. The output, will show the 3 digit number combinations to play in the upcoming drawings. Below is the manual method. Real example 4/11/2022 Virginia had 429 429 ------ first do this using last number drawn 429 4+2=6 2+9=1 ------ now do this 4 2 9 6 1 pair from adding 4+2 and 2+9 above. *See note below for double digit sums. ------ next 6+4=0 Note: 6+4 = 10. For Double digit sums, use only the right hand digit in this case is 0. 6+2=8 2+1=3 1+9=0 the 0 and 8, and 3 and 0 from adding the above, make pairs for below ------ now do this 4, 2, 9 6 1 0 8 3 0 ------ Pairs = 61 08 30 Digits = 4,2,9 these pairs and digits from above make the 3 digit combinations below. ------ Only (9) pick 3 Combo's to play 614 612 619 084 082 089 304 302 309
