| 92 | This was quite fun! For part 1, I iterate over the rows of the diagram | ||
| 93 | keeping a list of the position currently occupied by a tachyon. I use a | ||
| 94 | Python set to avoid duplicates. Part 2 is very similar, but the set is | ||
| 95 | changed to a map where the keys are the positions and the values are the | ||
| 96 | number of multiverses where a tachyon is in that position. To update | ||
| 97 | this value for the current row, I sum the values of all tachyons that | ||
| 98 | end there from the previous row (that can be one or two tachyons). | ||
