  1. notPaired [CF]

    Author Question: Lepluto

    In Numberland, every integer living there has a soulmate which is the exact same number. To prevent family disasters, the Numberland mayor made sure that there is no more than two of a certain number. However, he clearly forgot to create a pair for one of the numbers, making it very sad and lonely. Given the array representing Numberland’s citizens, your task is to find which number you need to add to the array so that everyone has a pair.

  2. Reverse Bit [CF]

    Author Question: Giappi

    I have an integer number, which I want to reverse by following steps:

    1. Convert the number into binary string.
    2. Reverse binary string.
    3. Convert the reversed binary string back to integer.

    Can you help me write a function to do it ?

  3. Python Simple Ciphertext

    Simply how to make a ciphertext only with 1 line. in this sample, the plaintext is result encoded from hexa. and then, just changing all integer 3 to 6 and also otherwise from 6 to 3.

    >>> #hex_encode = 'summonagus'.encode('hex')
    >>> hex_encode = '73756d6d6f6e61677573'
    >>> chip  = ''.join([ str(int(a)*2) if a.isdigit() and int(a) == 3 else str(int(a)/2) if a.isdigit() and int(a) == 6 else a for a in hex_encode ])
    >>> 
    >>> hex_encode
    '73756d6d6f6e61677573'
    >>> chip
    '76753d3d3f3e31377576'
    >>> 
    >>> 
    
  4. Python Crazy Decrypter has been Released

    Hello gays, this night i want to share my Python Crazy Decrypter tool. Python Crazy Decrypter is real crazy tool to decrypt md5, sha1, sha224, sha256, sha384, and sha512 with Brute Force method. Like most hashes Decrypter we know used the database to check the hash is valid or not.
