[old] Word Pattern

[old] Word Pattern

Undefined

Sophia's drones are too simple and can recognize symbols in only single words, digits or letters. She wants to teach the drones to understand basic commands which are represented as "words" consisted by letters and digits. For that, Sophia has uploaded "patterns," which describe the sequence of digits and letters in the command. Unfortunately,...

For example. The pattern is 42 and the command is "12a0b3e4".
42 == 101010 in binary form, but this is not enough of length. Let's append zeroes -- "00101010". Then compare: 
      42 == 00101010
12a0b3e4 == DDLDLDLD
--------------------
    True    VVVVVVVV
One more example -- 101 and "ab23b4zz": 
     101 == 01100101
ab23b4zz == LLDDLDLL
--------------------
   False    XVXVXXXV

Input: Two arguments. A pattern as a positive integer and a command as a string.

Output: Is the pattern coincide with the command or not as a boolean.

Example: 

checkCommand(42, "12a0b3e4") == true
checkCommand(101, "ab23b4zz") == false

How it is used: In this mission you can learn how to store more complex data in simple numbers and how to work with simple patterns. You can expand this concept and use more complex patterns (think about another number systems).

Precondition: 0 ≤ pattern < 231
0 < len(command) < 32
"command" contains only ASCII letters or digits.
