A database is a structured collection of data that is organized and managed to provide efficient retrieval and storage.
A database is a software system that stores and manages data.
It provides a way to organize and structure data for easy retrieval and manipulation.
Databases can be relational, object-oriented, or hierarchical.
Examples of databases include MySQL, Oracle, and MongoDB.
Quick sort is a sorting algorithm that uses a divide-and-conquer approach to sort an array of elements.
It selects a pivot element and partitions the array into two sub-arrays, one with elements smaller than the pivot and the other with elements greater than the pivot.
The process is repeated recursively on the sub-arrays until the entire array is sorted.
It has an average time complexity of O(n log n) and is widely used

I applied via Naukri.com and was interviewed in Oct 2023. There were 4 interview rounds.
Basic apti questions were asked
Sorting is the process of arranging elements in a specific order, typically ascending or descending.
Sorting is used to organize data for easier retrieval and analysis.
Common sorting algorithms include bubble sort, insertion sort, and quicksort.
Sorting can be done on various data structures, such as arrays, lists, and trees.
Example: Sorting an array of strings alphabetically.

A generic swap function swaps two values of any data type.
The function should take two parameters of any data type.
Use a temporary variable to store the value of one parameter.
Assign the value of the second parameter to the first parameter.
Assign the value of the temporary variable to the second parameter.
Search for an element in a rotated sorted linked list.
Find the pivot point where the list is rotated.
Divide the list into two sublists based on the pivot point.
Perform binary search on the appropriate sublist.
Handle edge cases such as empty list and list with only one element.
Search an element in a rotated sorted array
Find the pivot point where the array is rotated
Divide the array into two sub-arrays based on pivot point
Perform binary search on the appropriate sub-array
Repeat until element is found or sub-array size is 1
Find 5 missing numbers in an array of size 95 containing numbers in range 1 to 100.
Create a boolean array of size 100 and mark the present numbers
Iterate through the boolean array and find the missing numbers
Alternatively, use a HashSet to store the present numbers and find the missing ones
Given a Sudoku board, find possible numbers for an empty cell.
Iterate through empty cells and check possible numbers using row, column, and box constraints.
Use a set to keep track of possible numbers for each empty cell.
Return the set of possible numbers for the given empty cell.
Find integer average of 4 unsigned integers without typecasting
Add all the integers and divide by 4
Use bit shifting to divide by 4
Handle overflow by using long long data type
Use unsigned int data type for input
Code to identify 32 bit or 64 bit architecture of a processor
Check if the operating system is 32 bit or 64 bit
If OS is 32 bit, processor is 32 bit
If OS is 64 bit, check if processor supports 64 bit architecture
Use CPUID instruction to check if processor supports 64 bit architecture
Convert binary number to base 64 integer
Divide the binary number into groups of 6 bits
Convert each group of 6 bits to decimal
Map the decimal value to the corresponding base 64 character
Concatenate the base 64 characters to form the final integer

Check if left child is less than right child in a binary tree
Traverse the tree recursively and compare left and right child values
Use a stack to traverse the tree iteratively and compare left and right child values
Return true if all left children are less than right children, else false
Use built-in string method to check substring presence for faster execution.
Use 'indexOf' method to check if substring is present in the main string.
If the method returns -1, the substring is not present.
If the method returns a non-negative integer, the substring is present.
