4. The Two Sum problem is defined as: Given two unsorted arrays A 1 and A2, and an integer x, find the set SUM2 consisting of all pairs of values (a 1. a 1), where al eAl and a 2EA2,such that a 1+a2-x. The following algorithm is a solution to the Two Sum problem: SUM2ALGORITHM (A1, A2, x) 2. For each value, v1, in A1: 4. Search array A2 for value v2. If v2 is found in A2: 6. return SUM2 1: Fur each value, v. in A1: Add the pair (v1, v2) to SUM2 Notice that the efficiency of the algorithm will depend on the efficiency of th line 6. Assume a (very inefficient) search called SLOW SEARCH is used, which has a best case running time e(n) and a worst case running time 0(a2). What is the big-0h running time of the e Search performed on SUM2ALGORTHM algorithm if we use SLOW,SEARCH
