Let’s suppose that a palindromic number or numeral palindrome is a number of at least two characters  that remain the same when its digits are reversed. For example number 1221 is a palindrome while number  isn’t.
Let’s call a palindrome2 a Base 10 (decimal) palindrome the Base -2 (binary) representation of which is also a palindrome. For example number 33 is a palidrome2 since its Base-2 (binary) representation (100001) is also a palindrome. In the first million of natural numbers there will be so many as ____ palindrome2.

There are five masks to filter the file names. Arrange these masks in an ascending order of the number of file name that will be appropriately-placed by every mask.

There is a certain IP-based network that has its address and a mask. Nodes with addresses 192.168.163.17 and 192.168.173.19 are included into the network. Based in this information the network has the following address and mask …

Here is a fragment of e-table in which the cells of A1:C8 range contain only 0 or 1 numbers as it is shown in the picture. The following formula was input into cell D1 =if(and(B1=X;or(A1=Y; C1=Z));0;1) in which x, y and z were represented by 0 or 1. After that the cell D1 was copied into cells of D2:D8 range. As a result the following values were obtained:
 

The values input instead X, Y and Z were as follows … (Give your answer of X, Y and Z values separated by comma, for example: 1,0,1).
