2. Consider the following algorithm. Array A[0..n – 1] contains n integers. Algorithm choose (A) { n = A.last for (i = 0 to n-2) { min = i %3D for (j if (A[j] < A[min]) { min = j } } swap (A, i, min) } } = i+1 to n-1) { a) What does this algorithm compute? Describe the strategy of the algorithm. b) Trace the steps of the algorithm on the following array: 71 59 23 30 | 8 28 c) Use the big-Oh notation to express its computational complexity.
