Triple Sum Problem Statement

Bojack wants to gift Todd a binary tree with N nodes for his birthday. However, the tree is too large, so he decides to select exactly three nodes such that their sum equals a given integer X. Help Bojack determine if such a selection of nodes is possible.

Input:

1. An integer T representing the number of test cases. 2. For each test case: - The elements of the binary tree in level order, separated by spaces. - An integer X.

Output:

A boolean True or False for each test case, indicating the possibility of obtaining the sum X using values from any three nodes.

Example:

Input:

T = 1 Nodes = [2, 3, -1, 4, -1, -1, 5, -1, -1, -1] X = 11

Output:

True

Explanation:

The nodes with values 7, 3, and 1 add up to 11, making it possible to form the sum X.

Constraints:

1 ≤ T ≤ 100

1 ≤ N ≤ 3000

1 ≤ NodeVal ≤ 1000

1 ≤ X ≤ 1000

Time Limit: 1sec

Note:

You do not need to print anything. Just implement the function and return the correct output.

Input:

1. An integer T representing the number of test cases.
2. For each test case:
  - The elements of the binary tree in level order, separated by spaces.
  - An integer X.

Output:

A boolean True or False for each test case, indicating the possibility of obtaining the sum X using values from any three nodes.

Example:

Accepted Answer

The task is to determine if it is possible to select three nodes from a binary tree such that their sum equals a given value.

Traverse the binary tree and store all the node values in an array
Use three nested loops to iterate through all possible combinations of three nodes
Check if the sum of the three nodes equals the given value
If a valid combination is found, return True
If no valid combination is found, return False
