Summary
This PR exports the string hash implementation (RabinHash32) to a CLI utility. This is useful for generating random expected outputs to test the Golang implementation.
Motivation
In COOL, the hash function for string values is implemented by an existing RabinHashFunction32 class.
https://rabinhash.sourceforge.net/com/planetj/math/rabinhash/RabinHashFunction32.html
Since there is no equivalent implementation in Go, we need to port it ourselves (or LLM, of course).
Therefore, in order to test its correctness, we need to ensure that we can generate the same output as those in Java.
Usage
Run
scripts/rabinhash-rand-gen.sh Nto generateNinput-output pairs, separated by spaceThe output is written in hex format. This makes it easy to read in both int32 and uint32.
