Suppose you need a new operation for the max priority queue (stored as an array). We will call it changeKey. The idea is this. You have a priority queue (implemented as an array) to give out scholarships based on ACT. Someone retakes the ACT test and their score improves. You want to adjust the tree to accommodate this change. Assuming LOC is the position of the record in the array which has an improved key. How would you update the max priority queue
