SAT is a problem that has NP-Complete complexity, where the only way to solve the problem is to try all the possibilities and check which one is correct. [LO 1, LO 2, LO 3 & LO 4,] Briefly explain how you use Strongly Connected Component (SCC) to solve the special case of the Boolean Satisfiability Problem, namely 2-SAT (https://en.wikipedia. org/wiki/2-SAT) . This solution has linear complexity. NOTE LO1: Explain fundamental concept of analysis arithms. LO2: Apply algorithm techniques and methods. LO3: Solve a problem using specific algorithm. LO4: Compare several algorithm design methodsarrow_forwardConsider the following segment of code. Assume that i, z, and n are integers, and that n ≥ 0. . State a non-trivial loop invariant (must include two conditions: one each for i and 2). • Prove the invariant. A correct proof using an incorrect invariant would still receive credit. . Be sure the proof includes the final conditions after the loop has ended. Show the final value of z in terms of n. // (n ≥ 0) i = 0; x = 3; 11 while iarrow_forward
