When practicing, divide your page in half. On the left side, write your formal mathematical statements and symbols. On the right side, write the prose explanation or the justification (e.g., "by definition of an even number," or "by inductive hypothesis"). This forces you to separate the logical derivation from the linguistic presentation, ensuring your proofs are mathematically sound. Step 3: Use the "Bottom-Up, Top-Down" Strategy
A valid loop invariant is: result == (i-1)! and 1 <= i <= n+1 . Check this invariant before the loop, after each iteration, and after the loop ends to prove the algorithm's correctness.
