You can +use a `Counter("")` to count all chars with the string in a dict-like +type. In the next step we just `sum()` a list comprehension which +filters for either 2 or 3. Lastly we multiply both to find the +checksum. + +### Part Two +For this i settled for a simple for loop. The two interesting parts are +that we first ignore identical IDs since we don't want to compare the +same element to itself and we transform the strings into lists, since we +can not subindexes on strings. |
