**Question:** What is the height of the tree?**Tree Diagram:** - The diagram depicts a binary tree with the following structure: - The root node is `16`. - The left child of the root is `4`, which has a left child `12`. - The right child of the root is `21`, which has a right child `30`. The node `30` has a left child `28`.**Height Calculation:**- The height of a tree is the number of edges on the longest path from the root to a leaf.- Here, the longest path from the root `16` is: - `16` to `21` to `30` to `28`, which has three edges.**Answer Choices:**- 2- 3 (selected)- 4- 1**Correct Answer: 3** **Question:** What is the pre-order traversal of the binary tree T?**Diagram Explanation:** The binary tree diagram has nodes arranged as follows:- The root node is 16.- The left child of 16 is 4.- The left child of 4 is 12.- The right child of 16 is 21.- The right child of 21 is 30.- The left child of 30 is 28.**Answer Choices:**- ○ 16, 4, 12, 21, 30, 28- ○ 4, 12, 16, 21, 28, 30- ● 16, 4, 21, 12, 30, 28- ○ 12, 4, 28, 30, 21, 16**Correct Answer:** The selected correct answer is: **16, 4, 21,12,30,28**

I am what you call a perfectionist. I always strive for perfection, and I appreciate everyone and everything that is perfect. That is why I have recently acquired an appreciation for perfect numbers! I absolutely need to know which numbers from 1 to 1000 are considered perfect. From what I recall, a perfect number is a positive integer that is equal to the sum of all its divisors other than itself. Example: 6 is a perfect number because the divisors of 6 other than itself are 1, 2, and 3, and 1 + 2 + 3 = 6. c++ code

Correct answer will be upvoted else Multiple Downvoted. Computer science. You are remaining on the OX-hub at point 0 and you need to move to an integer point x>0. You can take a few leaps. Assume you're at present at point (y might be negative) and hop for the k-th time. You can: either leap to the point y+k or on the other hand leap to the point y−1. What is the base number of hops you want to arrive at the point x? Input The main line contains a solitary integer t (1≤t≤1000) — the number of experiments. The solitary line of each experiment contains the single integer x (1≤x≤106) — the objective point. Output For each experiment, print the single integer — the base number of leaps to arrive at x. It very well may be demonstrated that we can arrive at any integer point x.
