@code_report One of your C++ one partitions into 1111000 and then rotates the whole thing into 1110001.
Don't you only need to swap the last 1 and the last 0?

out.resize(n-1, '1');
out.resize(in.length() - 1, '0');
out.push_back('1');

@code_report Found a bug in CBQN from thinking '0'+1e4⥊1‿0 shouldn't be as slow as it was! So on latest develop ('0'+1⌽·∨'1'⊸=) is a concise-ish fast option utilizing bitarrs (("01"⊏˜1⌽·∨'1'⊸=) about as fast for without the fix); still a bit slower than the fully-manual one though.
