+# TASK #1
+# Cryptic Message
+# The communication system of an office is broken and message received are not
+# completely reliable. To send message Hello, it ended up sending these following:
+#
+# H x l 4 !
+# c e - l o
+# z e 6 l g
+# H W l v R
+# q 9 m # o
+# Similary another day we received a message repeatedly like below:
+#
+# P + 2 l ! a t o
+# 1 e 8 0 R $ 4 u
+# 5 - r ] + a > /
+# P x w l b 3 k \
+# 2 e 3 5 R 8 y u
+# < ! r ^ ( ) k 0
+# Write a script to decrypt the above repeated message (one message repeated 6
+# times).
+#
+# HINT: Look for characters repeated in a particular position in all six messages
+# received.
