By following these resources and practicing regularly, you can develop a deep understanding of discrete mathematics and proof and excel in your computer science career.

Inductive step : Let T be a tree with k + 1 vertices. Remove any leaf v (exists by tree property). T − v is a tree (still connected, no cycles) with k vertices. By IH, |E(T − v)| = k − 1. Adding back v adds exactly 1 edge (the incident edge to its unique neighbor). Thus |E(T)| = (k − 1) + 1 = k = (k + 1) − 1. ∎ By following these resources and practicing regularly, you
