Q1. 1. Variant of Binary Search
Ans. 
Variant of Binary Search
• Implement a binary search with a twist, such as searching for a range of values instead of a single value

• Modify the binary search algorithm to handle duplicates in the array

• Consider implementing a binary search for a rotated sorted array

Q1. Write algo to find the next element of a given value x in a sorted array?
Ans. 
Find the next element of a given value x in a sorted array using binary search for efficiency.
• Use binary search to find the index of x in the sorted array.

• If x is found, check the next index for the next element.

• If x is not found, the next element is the smallest element greater than x.

• Example: For array [1, 3, 5, 7] and x = 5, the next element is 7.

• Example: For array [1, 2, 4, 6] and x = 3, the next element is 4.

Q3. Steps of cloning?
Ans. 
Cloning involves the process of creating a genetically identical copy of an organism.
• Isolate the DNA from the organism to be cloned

• Insert the DNA into a vector, such as a plasmid

• Introduce the vector into a host cell, such as a bacteria or yeast

• Allow the host cell to replicate, creating multiple copies of the DNA

• Grow the host cell into a full organism with the same genetic makeup as the original

Q1. What is the implementation of a circular queue using structures in C and classes in C++?
Ans. 
Implementing a circular queue using structures in C and classes in C++ for efficient data management.
• A circular queue uses a fixed-size array and wraps around when the end is reached.

• In C, define a structure with front, rear, and size attributes.

• In C++, use a class to encapsulate queue operations and maintain data integrity.

• Both implementations should include functions for enqueue, dequeue, and checking if the queue is...read more

Q2. Sort a vector of strings alphabetically
Ans. 
Sort a vector of strings alphabetically using standard sorting algorithms.
• Use built-in sorting functions like std::sort in C++ or Collections.sort in Java.

• Example in Python: sorted(['banana', 'apple', 'cherry']) returns ['apple', 'banana', 'cherry'].

• Consider case sensitivity; 'Apple' and 'apple' may be treated differently.

• For custom sorting, provide a key function to define sorting criteria.
