Step 4
E sits between B and C, so E at position... wait, B is at 3, C is at 4, so E cannot sit between them as they are adjacent. Re-check: E sits between B(3) and C(4) means there's an error in our arrangement.
Correct approach: If E is between B and C, and B is 3rd from left, then arrangement could be B-E-C. So B(3), E(4), C(5). But A is 2nd from right (position 5). This means A and C both at position 5 - impossible.
Re-reading: A at position 5, so C at position 4 (immediate left), E must be at position 2 (only position between B and C if we consider the linear sequence).
Final check and arrangement: Position 1(?), B(2), Position 3(?), C(4), A(5), Position 6(?). E between B and C means E at position 3. Remaining positions filled by D and F.
Shortcut 3 - Reference Point Method: Pick one person with maximum clues as reference point. Build the entire arrangement around that person.
