[MCU] How exactly did Strange keep track of fourteen million possible outcomes while ensuring there were no duplicates?

He didn't have pen and paper or a computer, so how did he even count that exact number, much less know he was trying something completely different each time?  

A million alternatives is probably impossible to keep all in your head no matter how good your memory is.

1. He had the power of an infinity stone, the time stone to be precise, so human limitations don't matter.  
2. It doesn't matter if some of the outcomes are duplicates, he only looked for one where *they* win, everything else was obviously a failure for him  
3. He is a sorcerer, he does magic and maybe there is a memory spell?
