Find the smallest positive integer that cannot be expressed as the sum of elements from any proper subset of a non-decreasing sorted array of positive numbers.
Start with the smallest possible sum that can be represented, which is 1.
Iterate through the array and update the smallest sum that cannot be represented.
Return the final smallest sum that cannot be represented.

- Ans.
BFS traversal of an undirected and disconnected graph starting from vertex 0.
Implement BFS algorithm to traverse the graph starting from vertex 0.
Use a queue to keep track of visited nodes and their neighbors.
Ensure to visit all connected components of the graph.
Print the BFS traversal sequence for each test case in a separate line.
Handle cases where not all vertices are reachable from vertex 0.

Mostly technical and System Design questions were asked.
- Q1. Design an LRU (Least Recently Used) cache.
- Ans.
Design an LRU cache to store least recently used items efficiently.
Use a combination of a doubly linked list and a hashmap to store and retrieve items in O(1) time complexity.
When an item is accessed, move it to the front of the linked list to mark it as the most recently used.
If the cache is full, remove the least recently used item from the end of the linked list and the hashmap.

- Q1. Design a stack that support getmin in O(1) time and O(1) space complexities
- Ans.
Design a stack that supports getmin in O(1) time and O(1) space complexities.
Use two stacks, one for storing the actual values and the other for storing the minimum values.
When pushing a new value, check if it is smaller than the current minimum value and push it to the minimum stack if it is.
When popping a value, check if it is the current minimum value and pop it from the minimum stack if it is.
To get the minimum val...

- Q3. Binary tree traversal
- Ans.
Binary tree traversal is the process of visiting each node in a binary tree exactly once in a specific order.
There are three main types of binary tree traversal: inorder, preorder, and postorder.
Inorder traversal visits the left subtree, then the root, then the right subtree.
Preorder traversal visits the root, then the left subtree, then the right subtree.
Postorder traversal visits the left subtree, then the right subt...
- Q4. LRU cache explanation
- Ans.
LRU cache is a data structure that stores the most recently used items and discards the least recently used items.
LRU stands for Least Recently Used
It has a fixed size and when the cache is full, the least recently used item is removed to make space for a new item
It uses a combination of a doubly linked list and a hash map to achieve O(1) time complexity for both insertion and deletion
Example: A web browser cache that ...
