To determine which of the given sequences list nodes in the order in which we could have encountered them in the search for the key 273 in a Binary Search Tree (BST), we need to understand the properties of a BST and how the search process works.
Binary Search Tree (BST) Properties:
1. The left subtree of a node contains only nodes with keys lesser than the node's key.
2. The right subtree of a node contains only nodes with keys greater than the node's key.
3. Both the left and right subtrees must also be binary search trees.
Search Process in a BST:
1. Start at the root node.
2. If the key being searched is equal to the current node's key, the search is successful.
3. If the key being searched is less than the current node's key, move to the left child node.
4. If the key being searched is greater than the current node's key, move to the right child node.
5. Repeat steps 2-4 until either the key is found or a null child is encountered, indicating an unsuccessful search.
Analyzing the Given Sequences:
I. 81, 537, 102, 439, 285, 376, 305
II. 52, 97, 121, 195, 242, 381, 472
III. 142, 248, 520, 386, 345, 270, 307
IV. 550, 149, 507, 395, 463, 402, 270
In order for a sequence to list nodes in the order we could have encountered them in the search for the key 273, it must follow the BST search process. Let's analyze each sequence:
I. 81, 537, 102, 439, 285, 376, 305
- This sequence does not follow the BST search process. It jumps from 81 to 537 without exploring the left subtree of the root node.
II. 52, 97, 121, 195, 242, 381, 472
- This sequence follows the BST search process and could be encountered during the search for key 273. It explores the left subtree of the root node and reaches nodes in increasing order.
III. 142, 248, 520, 386, 345, 270, 307
- This sequence follows the BST search process and could be encountered during the search for key 273. It explores the right subtree of the root node and reaches nodes in decreasing order.
IV. 550, 149, 507, 395, 463, 402, 270
- This sequence does not follow the BST search process. It jumps from 550 to 149 without exploring the right subtree of the root node.
Based on the analysis, only sequences II and III list nodes in the order we could have encountered them in the search for the key 273 in a BST. Therefore, the correct answer is option 'D' - III only.
Binary Search Tree (BST) Properties:
1. The left subtree of a node contains only nodes with keys lesser than the node's key.
2. The right subtree of a node contains only nodes with keys greater than the node's key.
3. Both the left and right subtrees must also be binary search trees.
Search Process in a BST:
1. Start at the root node.
2. If the key being searched is equal to the current node's key, the search is successful.
3. If the key being searched is less than the current node's key, move to the left child node.
4. If the key being searched is greater than the current node's key, move to the right child node.
5. Repeat steps 2-4 until either the key is found or a null child is encountered, indicating an unsuccessful search.
Analyzing the Given Sequences:
I. 81, 537, 102, 439, 285, 376, 305
II. 52, 97, 121, 195, 242, 381, 472
III. 142, 248, 520, 386, 345, 270, 307
IV. 550, 149, 507, 395, 463, 402, 270
In order for a sequence to list nodes in the order we could have encountered them in the search for the key 273, it must follow the BST search process. Let's analyze each sequence:
I. 81, 537, 102, 439, 285, 376, 305
- This sequence does not follow the BST search process. It jumps from 81 to 537 without exploring the left subtree of the root node.
II. 52, 97, 121, 195, 242, 381, 472
- This sequence follows the BST search process and could be encountered during the search for key 273. It explores the left subtree of the root node and reaches nodes in increasing order.
III. 142, 248, 520, 386, 345, 270, 307
- This sequence follows the BST search process and could be encountered during the search for key 273. It explores the right subtree of the root node and reaches nodes in decreasing order.
IV. 550, 149, 507, 395, 463, 402, 270
- This sequence does not follow the BST search process. It jumps from 550 to 149 without exploring the right subtree of the root node.
Based on the analysis, only sequences II and III list nodes in the order we could have encountered them in the search for the key 273 in a BST. Therefore, the correct answer is option 'D' - III only.
