3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function. Sample calls should look like this. >>> lookup_friends_heights([{"name":"todd","height":170},{"name": "sarah", "height":165},{"name":"dweezil", "height":175}], ["dweezil", "sarah"]) [175, 165] >>> lookup_friends_heights([{"name": "todd","height":170},{"name": "sarah","height":165},{"name": "dweezil", "height":175}], %3D ["sarah", "elíza", "dweezil"]) [165, None, 175]

Q2: a. Write an algorithm that searches a sorted list of n items by dividing it into three sublists of almost n/3 items. This algorithm finds the sublist that might contain the given item and divides it into three smaller sublists of almost equal size. The algorithm repeats this process until it finds the item or concludes that the item is not in the list. Dry run the above algorithm to find the value 240. A[] = {10,15,20,60,65,110,150,220,240,245,260,290,300,460,470,501}
Select all statements that are true: Select(A,i) returns the i-th order statistic Calling Select(A,n/2) returns the median element if n is odd in O(n) time Select(A,i) returns the i-th element The Select() function can only work on an array of distinct elements Select(A,1) returns the minimum element in A
