the function hash logic is a lambda function that takes 3 arguments freq1, freq2, offset. inside this function: -the string f"{freq1}|{freq2}|{offset}" is created, concatenating the three arguments separated by the pipe character |. -then it is encoded to byte datatype using UTF-8 encoding -the hashlib.sha1() computes the hash for this encoded string -the hex digest function is called to convert this hash value to hexadecimal format -finally the hexadecimal hash is sliced including only the first 25 characters to save memory
