F. Top layer corners

Your goal now is aligning the corners.

• If you can match 4 corners as shown above, skip to next stage.
• If you can match 2 corners, hold the cube in such way that the matched corners are at the back and the unmatched are at the front, as shown below.
• If no corners are matched, apply the algorithm twice. Once regardless of the cube alignment and once as stated before.
• Apply the Corners swap algorithm:
