I have resolved the comments and added tests. Please have a look again

Looks good, thanks! And sorry for the delay in reviewing.

Please fix the lint errors and then we're good to merge.

I have run gofmt -s -w $files, it should be fixed now

[mbrt]

Uhm, @izidormatusov it looks like the check still fails. Could you double check?

[izidormatusov]

Forgot to add the formatted files into the commit 🤦 Should be fixed now

[mbrt]

More files need to be fixed. I suggest running go fmt ./... or configuring your editor to do it for you at every save. Note that it looks like internal/graph/munkres.go will be fixed too (I excluded the graph package from lint checks as it's a vendored dependency). You can decide whether to keep that change in the PR or not, up to you.

Ah, nevermind. I could fix it myself quickly. Thanks for the contribution!
