+- Task 1: We use awk to find the maximum while we iterate through over the file
+- Task 2: We use awk again for summing the calories, then sort them and take the top 3 which we again sum up with awk
 ```shell
 # Find the Elf carrying the most Calories. How many total Calories is that Elf carrying?

+We use that chars are just numbers, so we can easily convert them into the respective points by just subtracting `'A'` or `'X'`.
+The rest is then just a few `if else`s.

+All the characters (the Elf's items) occuring in (half) a line (backpack) are stored as bits in an unsigned long, duplicate characters can then be determined by bitwise and-ing these numbers.
