+#
+# Write a script to simulate the addition of the given binary numbers.

+# The script should simulate something like $a + $b. (operator overloading)
+#
+# Example 1
+# Input: $a = 11; $b = 1;
+# Output: 100
+# Example 2
+# Input: $a = 101; $b = 1;
+# Output: 110
+# Example 3
+# Input: $a = 100; $b = 11;

+# Submitted by: Mohammad S Anwar

+# Now the 4th element in the table is "3".
