+# TASK #1 - Search Matrix
+# Submitted by: Mohammad S Anwar
+# You are given 5x5 matrix filled with integers such that each row is sorted
+# from left to right and the first integer of each row is greater than the
+# last integer of the previous row.
+#
+# Write a script to find a given integer in the matrix using an efficient
+# search algorithm.
+#
+# Example
+# Matrix: [ 1, 2, 3, 5, 7 ]
+# [ 9, 11, 15, 19, 20 ]
+# [ 23, 24, 25, 29, 31 ]
+# [ 32, 33, 39, 40, 42 ]
+# [ 45, 47, 48, 49, 50 ]
+#
+# Input: 35
+# Output: 0 since it is missing in the matrix
+#
+# Input: 39
+# Output: 1 as it exists in the matrix
