[ < r-1 - l. It is always good practice to prove properties in a goal-oriented way, working from complicated statements to simpler statements. In this case, the goal was to prove The strategy is to take the left side of this statement, since this is the more complicated side, and simplify it. In the process, we learn that the properties 0 < / and r ^ N are not relevant. Exercise 4.2.

Prove it also using that m+2 ^m/2 <= O^ra. (That is, integer division by 2 rounds down for positive m.) D Exercise 4.3.
