There are 5 children in a group, all of different heights. Can they stand such that four of them say 1 and the last one says 0? Why or why not?

  • -1

No, it’s not possible. If four children say ‘1’, they each need one taller neighbor. This would leave the tallest child with no taller neighbors, so they would say ‘0’.

  1. No, it’s impossible for four children to say ‘1’ and the last one to say ‘0’. If four children each say ‘1’, they would need exactly one taller neighbor. This implies the tallest child, with no taller neighbor, must say ‘0’. However, this arrangement conflicts with the condition for four children saying ‘1’. Such scenarios reveal the inherent dependency on height variations and positioning among the children.
