Step 1

Since all elements are distinct, the smallest element cannot be at the root or any higher level nodes, as those nodes will always have larger parent nodes. Show more…

Key Concepts

Max Heap A max heap is a type of binary tree-based data structure where each parent's value is greater than that of its children, ensuring that the maximum element is always at the root. This structure allows for efficient retrieval of the largest element. Heap Property The heap property is the ordering principle that requires each node to have a value that is at least as great as the values of its children (in a max heap). This property guarantees that the most significant element is positioned at the top of the structure. Complete Binary Tree A complete binary tree is one in which every level, except potentially the last, is completely filled, with nodes as far left as possible. This structural characteristic is vital for implementing heaps efficiently using array representations. Leaf Node Leaf nodes are the terminal nodes of a tree that do not have any child nodes. In a max heap, due to the heap property ensuring higher values near the root, the smallest element is likely to be one of these leaf nodes, especially since they are less constrained by the ordering compared to interior nodes.

Transcript

00:01 All right, so here we are finding the first occurrence of the largest element of a list, right? so the idea is that the same element could appear multiple times in the list, so we just want to find the first time it occurs. 00:17 So i'm going to call this procedure max because i'm a lazy writer. 00:22 I think the solution states that it's maximum. 00:26 And the input is going to be a list. 00:29 So n elements in this list, and these are integers, which i'm going to abbreviate as ints with n being greater than are equal to 1. 00:42 So we're just saying there has to be an element in the list, at least one of them. 00:47 So initially, we are going to define variable max and set it equal to 1...
