By a worst input (for the selection phase of Heapsort) of size n, we mean a heap of size n such that, if it is given to the selection phase of Heapsort, the number of movements of data is maximum among the numbers of movements for all heaps of size n. D.E. Knuth showed a special type of worst inputs which we will call the K-type heaps. His definition of K-type heaps was by the induction on the size n. We give one characterization of K-type worst heaps that is based on their tree structure. This characterization gives more information on the tree structure of K-type heaps than the Knuth's definition.
