A “postage stamp problem” is a problem that (typically) asks us to determine what total postage values can be produced using two sorts of stamps. Suppose that you have ¢ 3 ¢ stamps and ¢ 7 ¢ stamps, show (using strong induction) that any postage value ¢ 12 ¢ or higher can be achieved. That is,

Show that P(I) holds for all leaves I of a tree. And for each type of internal node t with subtrees s1...sn, show that P(s1) and P(sn) and so on implies P(t).

Inductive Step: Assume that we can form postage of j cents for all nonnegative integers j with j ≤ k us-ing just three-cent and four-cent stamps. We can then form postage of k +1 cents by replacing one three-cent stamp with a four-cent stamp or by replacing two four-cent stamps by three three-cent stamps. 33. frame shop on mass aveWebDec 25, 2024 · Structural induction is a generalization of the mathematical notion of induction.
