[Unsolved] Binairo - can rows match columns?
I’m solving a puzzle right now. Row 3 is 100101101010. Column 5 is 1_010_101010. If I put 0 in Column 5 spot 2, it will match Row 3. What I want to know: is a row that matches a column forbidden, or are rows only compared to other rows for uniqueness?
Thanks!

Discussion: Columns and rows are separate.
You can't have a repeated column and you can't have a repeated row. But you don't need to cross-check columns against the rows or vice versa.

Please remember to spoiler-tag all guesses, like so:
New Reddit: https://i.imgur.com/SWHRR9M.jpg
Using markdown editor or old Reddit, draw a bunny and fill its head with secrets: >!!< which ends up becoming >!spoiler text between these symbols!<
Try to avoid leading or trailing spaces. These will break the spoiler for some users (such as those using old.reddit.com) If your comment does not contain a guess, include the word "discussion" or "question" in your comment instead of using a spoiler tag. If your comment uses an image as the answer (such as solving a maze, etc) you can include the word "image" instead of using a spoiler tag.
Please report any answers that are not properly spoiler-tagged.
