What is a linked list in computer science?
✔✔ A data structure where each element, or node, contains a value and a reference to the next
node in the sequence.
What is the difference between a singly linked list and a doubly linked list?
✔✔ A singly linked list has nodes with a single reference to the next node, while a doubly linked
list has nodes with references to both the next and previous nodes.
What is the time complexity of accessing an element in an array?
✔✔ O(1), meaning it takes constant time to access an element by its index.
What is the time complexity of inserting an element at the beginning of a linked list?
✔✔ O(1), since you can insert the new node by adjusting the head reference.
How do you perform a breadth-first search (BFS) in a graph?
1
,✔✔ By using a queue to explore all nodes at the present depth level before moving on to nodes
at the next depth level.
How do you perform a depth-first search (DFS) in a graph?
✔✔ By using a stack (or recursion) to explore as far as possible along each branch before
backtracking.
What is a priority queue?
✔✔ A data structure where each element has a priority, and elements are dequeued based on
their priority rather than their order in the queue.
What is a graph's adjacency matrix?
✔✔ A square matrix used to represent a graph, where the element at row i and column j indicates
whether there is an edge between vertex i and vertex j.
What is the purpose of Dijkstra's algorithm?
✔✔ To find the shortest path from a source vertex to all other vertices in a weighted graph.
What is a dynamic programming approach?
2
, ✔✔ A method for solving complex problems by breaking them down into simpler subproblems
and storing the results to avoid redundant computations.
What is a stack in computer science?
✔✔ A data structure that follows the Last In, First Out (LIFO) principle.
What is a queue in computer science?
✔✔ A data structure that follows the First In, First Out (FIFO) principle.
How do you perform a push operation in a stack?
✔✔ By adding an element to the top of the stack.
What is the primary difference between a stack and a queue?
✔✔ A stack uses LIFO ordering, while a queue uses FIFO ordering.
What is a binary tree?
✔✔ A tree data structure where each node has at most two children.
