- Ans.
Find odd weight ball among 12 identical balls using a balance in minimum weighings.
Divide balls into 3 groups of 4 each
Weigh any 2 groups against each other
If both groups weigh the same, the odd ball is in the third group
If one group is heavier, weigh any 2 balls from that group against each other
If they weigh the same, the odd ball is the remaining one
If one ball is heavier, it is the odd ball
Repeat the process with t

- Ans.
BFS and DFS are graph traversal algorithms used to search for nodes in a graph.
BFS stands for Breadth First Search and explores all the nodes at the current depth before moving to the next level.
DFS stands for Depth First Search and explores as far as possible along each branch before backtracking.
BFS uses a queue data structure while DFS uses a stack or recursion.
BFS is useful for finding the shortest path in an unwei...
- Q13. 4. Which traversal would I prefer for finding a cycle in a graph?
- Ans.
I would prefer Depth First Search (DFS) traversal for finding a cycle in a graph.
DFS is better suited for finding cycles in a graph as it explores deeper into the graph before backtracking.
DFS can detect a cycle in a graph in O(V+E) time complexity.
DFS can be implemented using recursion or a stack.
Breadth First Search (BFS) can also be used to find cycles but it is less efficient than DFS.
In DFS, we can keep track of v
- Q14. Explain time and space complexities of hashmap
- Ans.
Hashmap has constant time complexity for insertion, deletion, and retrieval, but requires additional space.
Hashmap provides constant time complexity O(1) for insertion, deletion, and retrieval operations on average.
The space complexity of a hashmap is proportional to the number of elements stored in it.
Hashmap uses a hash function to map keys to indices in an underlying array, which allows for efficient lookup.
In case ...

- Q3. What is indexing in Database Management Systems (DBMS)?
- Ans.
Indexing in DBMS is a technique used to improve the performance of queries by allowing faster retrieval of data.
Indexes are data structures that store a small portion of the data set in an easily searchable format.
They help in speeding up the data retrieval process by reducing the number of disk accesses needed.
Indexes can be created on one or more columns of a table to improve the performance of SELECT queries.
