+# TASK #1
+# Merge Intervals
+# Write a script to merge the given intervals where ever possible.
+#
+# [2,7], [3,9], [10,12], [15,19], [18,22]
+#
+# The script should merge [2, 7] and [3, 9] together to return [2, 9].
+#
+# Similarly it should also merge [15, 19] and [18, 22] together to return
+# [15, 22].
+#
+# The final result should be something like below:
+#
+# [2, 9], [10, 12], [15, 22]
