B. 12 points each 4. P22: 2.1-3 2.1-3 Consider the searching problem: Input: A sequence of n numbers A = (a1, A2, ..., An) and a value v. Output: An index i such that v A[i] or the special value Nil if v does not appear in A. Write pseudocode for linear search, which scans through the sequence, looking for v. Using a loop invariant, prove that your algorithm is correct. Make sure that your loop invariant fulfills the three necessary properties. =
