// changeBit is a functio that function that flips a bit of the hash at a
// particular bit-index. You should be aware that the bit flipping in this
// function a bit strange, example:
// hash: [0b00000000, 0b00000000, ... 0b00000000]
// 0 1 ... 31

// byte: 0 0 0 0 0 0 0 0
// 7 6 5 4 3 2 1 0

// By flipping the bit at 7 position you will flip the first bit in hash and by
// flipping the bit at 8 position you will flip the 16 bit in hash.
