hey there! if constructor(bytes32[] memory proposalNames) {...} is given how should i pass arguments in remix ide (in web browser)? I tried [keccak256("hello"), keccak256("world")], and it says "Error encoding arguments:..." to me.

you should do the keccak BEFORE and use the output as parameter =)

cast k "hello"
0x1c8aff950685c2ed4bc3174f3472287b56d9517b9c948127319a09a7a36deac8

cast k "world"
0x8452c9b9140222b08593a26daa782707297be9f7b3e8281d7b4974769f19afd0

funny fact
those are also private keys and you can use them (of course don't!!)

ummm, and in what environment should i use cast k "hello"? it's not a terminal, right?

it's cast, a tool from Foundry-rs
