+# Task 1: Toeplitz Matrix
+# Submitted by: Mohammad S Anwar
+#
+# You are given a matrix m x n.
+# Write a script to find out if the given matrix is Toeplitz Matrix.
+# A matrix is Toeplitz if every diagonal from top-left to bottom-right has the same elements.
+#
+#
+# Example 1
+# Input: @matrix = [ [4, 3, 2, 1],
+# [5, 4, 3, 2],
+# [6, 5, 4, 3],
+# ]
+# Output: true
+#
+# Example 2
+# Input: @matrix = [ [1, 2, 3],
+# [3, 2, 1],
+# ]
+# Output: false
+
