+# 3
+
+We can simply parse the forest as an array of strings.
+The trees repeat infinitely to the right, this screams for a good mod.
+This means: `char = row[x % len(row)]`. No complex logic needed
+
+For the second one we simply automate the process and sum up the total.
+We can simply encode the coordinates as a function of the index we are current at.
