Professor Jagger proposes to show that SAT ≤P 3-CNF-SAT by using only the truth-table technique in the proof of Theorem 34.10, and not the other steps. That is, the professor proposes to take the boolean formula φ, form a truth table for its variables, derive from the truth table a formula in 3-DNF that is equivalent to ¬φ, and then negate and apply DeMorgan"s laws to produce a 3-CNF formula equivalent to φ. Show that this strategy does not yield a polynomial-time reduction.
