In a binary tree, a special node is a node that is the only child of its parent. The root of the tree is not special because it does not have a parent node. Node ‘1’ is always the root of the binary tree. Return an array/list containing the values of all special nodes in the tree.

Example:

Let’s say you have a binary tree as follows:-

Node 4 is a special node as it is the only child of node 2. Node 1 cannot be a special child as it does not have a parent. All the other nodes have a sibling i.e there parent has more than one child. Therefore return [4] as the answer.

Note:

Return the array/list containing special nodes in any order. 

You are given an array/list 'prices' where the elements of the array represent the prices of the stock as they were yesterday and indices of the array represent minutes. Your task is to find and return the maximum profit you can make by buying and selling the stock. You can buy and sell the stock only once.

Note:

You can’t sell without buying first.

For Example:

For the given array [ 2, 100, 150, 120],
The maximum profit can be achieved by buying the stock at minute 0 when its price is Rs. 2 and selling it at minute 2 when its price is Rs. 150.
So, the output will be 148.
