It does not, however, have a MonadFix instance. Is this because such an instance cannot be written, or was it just left out? If such an instance cannot be written, why not? 回答1: Consider the description of what mfix does: The fixed point of a monadic computation. mfix f executes the action f only once, with the eventual output fed back as the input. The word "executes", in the context of Free , means

The easy way would be to put all the chars in a stack and put them back into a string again but I doubt that's a very efficient way to do it. And please do not tell me to use some built in function in Java. I am interested in learning how to do it not to use an efficient function but not knowing why it's efficient or how it's built up. 回答1: You say you want to know the most efficient way and you don't want to know some standard built-in way of

I searched the documentation, but couldn't find anything the like.

Are passwords hashed with BCrypt always of same length? EDIT Example hash: $2a$10$KssILxWNR6k62B7yiX0GAe2Q7wwHlrzhF3LqtVvpyvHZf0MwvNfVu After hashing some passwords, it seems that BCrypt always generates 60 character hashes. EDIT 2 Sorry for not mentioning the implementation. I am using jBCrypt . 回答1: The modular crypt format for bcrypt consists of $2$ , $2a$ or $2y$ identifying the hashing algorithm and
