This Lua solution should work for this clash
s=io.read():gsub("%s", "") c=io.read"n" for i = 1, #s+#s%c, c do print(s:sub(i,i+c-1)) end
but it complains in 2 test cases and validators about a trailing newline.
The main problem here is that I can’t edit the clash. Why can’t I edit this clash? I can edit other clashes.
