**Migratory Birds**

### Problem Statement :

Given an array of bird sightings where every element represents a bird type id, determine the id of the most frequently sighted type. If more than 1 type has been spotted that maximum amount, return the smallest of their ids. Example arr = [1, 1, 2, 2, 3] There are two each of types 1 and 2, and one sighting of type 3. Pick the lower of the two types seen twice: type 1. Function Description Complete the migratoryBirds function in the editor below. migratoryBirds has the following parameter(s): int arr[n]: the types of birds sighted Returns int: the lowest type id of the most frequently sighted birds Input Format The first line contains an integer, n, the size of arr. The second line describes arr as n space-separated integers, each a type number of the bird sighted. Constraints 5 <= n <= 2 * 10^5 It is guaranteed that each type is 1, 2, 3, 4, or 5.

## Balanced Forest

Greg has a tree of nodes containing integer data. He wants to insert a node with some non-zero integer value somewhere into the tree. His goal is to be able to cut two edges and have the values of each of the three new trees sum to the same amount. This is called a balanced forest. Being frugal, the data value he inserts should be minimal. Determine the minimal amount that a new node can have to a

Jenny loves experimenting with trees. Her favorite tree has n nodes connected by n - 1 edges, and each edge is ` unit in length. She wants to cut a subtree (i.e., a connected part of the original tree) of radius r from this tree by performing the following two steps: 1. Choose a node, x , from the tree. 2. Cut a subtree consisting of all nodes which are not further than r units from node x .

An AVL tree (Georgy Adelson-Velsky and Landis' tree, named after the inventors) is a self-balancing binary search tree. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property. We define balance factor for each node as : balanceFactor = height(left subtree) - height(righ
