Hamming distance between i,j.Calculation of Hamming distance:1. If the hashcode is within 64 bits, the final computed hashsign can be expressed using the computer's built-in type, such as unsigned long.Then the Hashsig bitwise XOR of two objects, and the number of bits in the result is 1, which is the Hamming distance value.2. If the hashcode is greater than 64 bits, such as MD5, a composite structure is required to represent it. We can use char[16] to represent 128bit.Then, the Hamming distanc
