+## Day 2
+
+### Part One
+For this part i made use of a python standardlib functionality. 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.
