What is the value returned by the following function? Give your answer in terms of n. Express the running time using the Theta notation, clearly showing intermediate steps. HW1Q3(n) 840 for i=1 to n do for j = 1 to i do for k=j to i + j do 18+8+1 return s Suppose you are given a set of small boxes, numbered 1 to n, identical in every respect except that each of the first i contain a pearl whereas the remaining n-i are empty. You also have two magic wands that can each test whether a box is empty or not in a single touch, except that a wand disappears if you test it on an empty box. Show that, without knowing the value of i, you can use the two wands to determine all the boxes containing pearls using at most o(n) (i.e., "little-o" n) wand touches. Express, as a function of n, the asymptotic number of wand touches needed
