Consider a modification to the activity-selection problem in which each activity ai has, in addition to a start and finish time, a value vi. the objective is no longer to maximize the number of activities scheduled, but instead to maximize the total value of the activities scheduled. that is, we wish to choose a set a of compatible activities such that summation of their corresponding values is maximized. give a polynomial-time algorithm for this problem.

)a grad student comes up with the following algorithm to sort an array a[1..n] that works by first sorting the first 2/3rds of the array, then sorting the last 2/3rds of the (resulting) array, and finally sorting the first 2/3rds of the new array. 1: function g-sort(a, n) . takes as input an array of n numbers, a[1..n] 2: g-sort-recurse(a, 1, n) 3: end function 4: function g-sort-recurse(a, `, u) 5: if u â’ ` ≤ 0 then 6: return . 1 or fewer elements already sorted 7: else if u â’ ` = 1 then . 2 elements 8: if a[u] < a[`] then . swap values 9: temp â†a[u] 10: a[u] â†a[`] 11: a[`] â†temp 12: end if 13: else . 3 or more elements 14: size â†u â’ ` + 1 15: twothirds â†d(2 â— size)/3e 16: g-sort-recurse(a, `, ` + twothirds â’ 1) 17: g-sort-recurse(a, u â’ twothirds + 1, u) 18: g-sort-recurse(a, `, ` + twothirds â’ 1) 19: end if 20: end function first (5 pts), prove that the algorithm correctly sorts the numbers in the array (in increasing order). after showing that it correctly sorts 1 and 2 element intervals, you may make the (incorrect) assumption that the number of elements being passed to g-sort-recurse is always a multiple of 3 to simplify the notation (and drop the floors/ceilings).
