Given a binary tree of integers. All nodes in the binary tree have distinct values. You are given an integer B.
You have to find all the nodes that are at a distance of exactly C from the node containing value B.
Return an array of integers consisting all the nodes that are C distance from node containing value B.
You may return the nodes in any order.
Your solution will run on multiple test cases, if you are using global variables make sure to clear every time .
1 <= Number of nodes in binary tree <= 100000 0 <= Node values <= 10^9 0 <= B <= 10^9 0 <= C <= 100
Input 1: 1 / \ 2 3 / \ / \ 4 5 6 7 / 8 B = 3 C = 3 Output 1: [4, 5] Input 2: 1 / \ 2 3 \ 4 \ 5 B = 4 C = 1 Output 2: [2, 5]
NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a doubt? Checkout Sample Codes for more details.
