Q1. 
Rotting Oranges Problem Statement
You are given an undirected and disconnected graph G(V, E) with V vertices numbered from 0 to V-1 and E edges. Your task is to perform a BFS traversal starting from the 0...read more
Ans. 
Perform BFS traversal on an undirected and disconnected graph starting from vertex 0.
• Implement BFS traversal algorithm starting from vertex 0

• Use a queue to keep track of visited nodes and their neighbors

• Print the traversal order in sorted order for each node's connected nodes

Ans. 
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.

Q3. 
BFS Traversal in a Graph
Given an undirected and disconnected graph G(V, E) where V vertices are numbered from 0 to V-1, and E represents edges, your task is to output the BFS traversal starting from the ...read more
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. Sorting an array
Ans. 
Sorting an array of strings
• Use Arrays.sort() method to sort the array of strings

• You can also use a custom Comparator to define the sorting order

• Example: String[] arr = {"banana", "apple", "orange"}; Arrays.sort(arr);
