FAQ
Q: What is an array?
A: An array is an ordered collection of data types with indexing starting from zero.
Q: Can you explain zero-based counting in arrays?
A: Zero-based counting means that the first element in an array is located at index 0.
Q: What types of values can arrays hold?
A: Arrays can hold various types of values including text, boolean, and numeric data.
Q: How does memory allocation work in arrays?
A: Arrays allocate memory based on the data elements they store and their efficiency in storing and accessing elements.
Q: What are linked lists and how do they differ from arrays?
A: Linked lists are data structures that excel in memory usage efficiency and operations like adding and deleting elements, unlike arrays which have fixed sizes.
Q: How do you construct a binary search tree starting with numbers like 20 and 15?
A: To construct a binary search tree, you compare numbers against existing nodes and place them accordingly; for example, larger numbers go to the right and smaller to the left.
Q: What happens when you add nodes with larger numbers like 25 and 33 to a binary search tree?
A: Nodes with larger numbers like 25 and 33 are placed in the binary search tree by comparing them with existing nodes and following the binary search process.
Q: How does the binary search process work in evaluating numbers and placing them in a binary search tree?
A: The binary search process involves comparing numbers with existing nodes to determine their placement in the tree, ensuring the tree remains sorted for efficient searching.
