+Task 1: Count Even Digits Number

+
+   You are given a array of positive integers, @ints.
+
+   Write a script to find out how many integers have even number of
+   digits.
+
+Example 1
+
+Input: @ints = (10, 1, 111, 24, 1000)
+Output: 3
+
+There are 3 integers having even digits i.e. 10, 24 and 1000.
+
+Example 2
+
+Input: @ints = (111, 1, 11111)
+Output: 0
+
+Example 3
+
+Input: @ints = (2, 8, 1024, 256)

+
+   You are given an array of integers, @int and an integer $k.
+
+   Write a script to find the sum of values whose index binary
+   representation has exactly $k number of 1-bit set.
+
+Example 1
+
+Input: @ints = (2, 5, 9, 11, 3), $k = 1
+Output: 17
+
+Binary representation of index 0 = 0
+Binary representation of index 1 = 1
+Binary representation of index 2 = 10
+Binary representation of index 3 = 11
+Binary representation of index 4 = 100
+
+So the indices 1, 2 and 4 have total one 1-bit sets.
+Therefore the sum, $ints[1] + $ints[2] + $ints[3] = 17
+
+Example 2
+
+Input: @ints = (2, 5, 9, 11, 3), $k = 2
+Output: 11
+
+Example 3
+
+Input: @ints = (2, 5, 9, 11, 3), $k = 0
+Output: 2
