    Speed tests of various implementations, mostly
    from http://stackoverflow.com/questions/9829578/fast-way-of-counting-bits-in-python
    
    Some of these functions work on arbitrary input, but some are specifically for
    32 bit integers, see the function sources for detail.

''' Solve systems of simultaneous linear congruences using the Chinese Remainder Theorem

    Chinese Remainder Theorem:
    If X = r_i mod m_i for i in 1..n, m_i pairwise coprime
    Let
    M_i = M // m_i, y_i = M_i^(-1) mod m_i, i.e., y_i * M_i = 1 mod m_i
    Then
    y_i * M_i = 0 mod m_j for j != i

''' Transform words into 1-based indices of their letters in alphabetical order.

    Eg 'APPLE' gets these indices: [(1, 'A'), (2, 'E'), (3, 'L'), (4, 'P'), (5, 'P')]
    So we encode 'APPLE' as (1, 4, 5, 3, 2)
