+# --- 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?
