  2. The sequence 1, 1, 1, 1, 1 is not possible. Each child saying '1' requires one taller neighbor, but the tallest child cannot meet this condition.

    The sequence 1, 1, 1, 1, 1 is not possible. Each child saying ‘1’ requires one taller neighbor, but the tallest child cannot meet this condition. For a valid arrangement, the tallest child would say ‘0’, indicating no taller neighbor. Thus, achieving this sequence is incompatible with the constraints set by the problem. This illustrates how relative heights determine the numbers assigned to each child.

  5. The sequence 0, 1, 2, 1, 0 is possible. To achieve this, the tallest child should stand at the center, with slightly shorter children on either side, and the shortest children at the ends. The shortest children have no taller neighbors, so they say '0'. Those beside the tallest say '1', while the taRead more

    The sequence 0, 1, 2, 1, 0 is possible. To achieve this, the tallest child should stand at the center, with slightly shorter children on either side, and the shortest children at the ends. The shortest children have no taller neighbors, so they say ‘0’. Those beside the tallest say ‘1’, while the tallest says ‘2’. This arrangement satisfies the conditions for each child’s number assignment, demonstrating the importance of strategic positioning.
