+Task 1: Consecutive One         Submitted by: Mohammad Sajid Anwar
+
+You are given a binary array containing only 0 or/and 1.
+Write a script to find out the maximum consecutive 1 in the given array.
+
+
+Example 1
+Input: @binary = (0, 1, 1, 0, 1, 1, 1)
+Output: 3
+
+Example 2
+Input: @binary = (0, 0, 0, 0)
+Output: 0
+
+Example 3
+Input: @binary = (1, 0, 1, 0, 1, 1)
+Output: 2

+Task 2: Final Price         Submitted by: Mohammad Sajid Anwar
+You are given an array of item prices.
+Write a script to find out the final price of each items in the given array.
+
+There is a special discount scheme going on. If there’s an item with a lower or equal price later in the list, you get a discount equal to that later price (the first one you find in order).
+
+Example 1
+Input: @prices = (8, 4, 6, 2, 3)
+Output: (4, 2, 4, 2, 3)
+
+Example 2
+Input: @prices = (1, 2, 3, 4, 5)
+Output: (1, 2, 3, 4, 5)
+
+Example 3
+Input: @prices = (7, 1, 1, 5)
+Output: (6, 0, 1, 5)
