+# TASK #1 › Majority Element
+# Submitted by: Mohammad S Anwar
+#
+# You are given an array of integers of size $N.
+#
+# Write a script to find the majority element. If none found then print -1.
+#
+#     Majority element in the list is the one that appears more than floor(size_of_list/2).
+#
+# Example 1
+# Input: @A = (1, 2, 2, 3, 2, 4, 2)
+# Output: 2, as 2 appears 4 times in the list which is more than floor(7/2).
+#
+# Example 2
+# Input: @A = (1, 3, 1, 2, 4, 5)
+# Output: -1 as none of the elements appears more than floor(6/2).
