+
+--- Day 6: Signals and Noise ---
+
+   Something is jamming your communications with Santa. Fortunately, your signal is only partially jammed, and protocol in situations like this is to switch to
+   a simple repetition code to get the message through.
+
+   In this model, the same message is sent repeatedly. You've recorded the repeating message signal (your puzzle input), but the data seems quite corrupted -
+   almost too badly to recover. Almost.
+
+   All you need to do is figure out which character is most frequent for each position. For example, suppose you had recorded the following messages:
+
+ eedadn
+ drvtee
+ eandsr
+ raavrd
+ atevrs
+ tsrnev
+ sdttsa
+ rasrtv
+ nssdts
+ ntnada
+ svetve
+ tesnvt
+ vntsnd
+ vrdear
+ dvrsen
+ enarar
+
+   The most common character in the first column is e; in the second, a; in the third, s, and so on. Combining these characters returns the error-corrected
+   message, easter.
+
+   Given the recording in your puzzle input, what is the error-corrected version of the message being sent?
+
+   Your puzzle answer was ________.
+
+--- Part Two ---
+
+   Of course, that would be the message - if you hadn't agreed to use a modified repetition code instead.
+
+   In this modified code, the sender instead transmits what looks like random data, but for each character, the character they actually want to send is
+   slightly less likely than the others. Even after signal-jamming noise, you can look at the letter distributions in each column and choose the least common
+   letter to reconstruct the original message.
+
+   In the above example, the least common character in the first column is a; in the second, d, and so on. Repeating this process for the remaining characters
+   produces the original message, advent.
+
+   Given the recording in your puzzle input and this new decoding methodology, what is the original message that Santa is trying to send?
+
+   Your puzzle answer was ________.
