Question # 01: Consider the searching problem: Input: A sequence of n numbers A = (a, a2, a3, ...., an ) 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.
