Return type:

bool

different_bit_index(x, y)

Returns the index of the lowest different bit.

Parameters:

• x (int)

• y (int)

Return type:

int

lowest_bit_index(x)

Returns the index of the lowest bit that is set.

Parameters:

x (int)

Return type:

parity_sign_of_bits(bits)

Returns a sign corresponding to parity of bits (even=1, odd=-1).

Parameters:

bits (int)
