Video Summary

The problem involves arranging birds named Ha, Long, Nha, and Trang on four parallel wires, considering specific constraints. By following logical deductions: Trang cannot be on the bottom wire due to birds below her, and Nha is above Trang due to fewer birds below Trang. Trang is placed on the third wire, with 3 birds there and 2 birds below on the fourth wire. Long, with 25 birds above, is on the bottom wire. Ha is placed on the second wire. The total configuration results in 27 birds in total, fulfilling all conditions. The solution is 27 birds.
