All questions depends on cloud
Delta in cloud refers to the difference between two versions of a file or data.
Delta is used to reduce the amount of data that needs to be transferred during updates or backups.
It helps in saving bandwidth and storage space.
For example, in cloud storage, only the changes made to a file are synced instead of the entire file.
Delta compression is also used in cloud computing to optimize network traffic and reduce latency.
Internet in the cloud enables access to web-based applications and services from anywhere in the world.
Cloud-based applications can be accessed through a web browser or mobile app
Internet connectivity is required to access cloud services
Cloud providers offer global data centers to ensure low latency and high availability
Examples include Google Drive, Dropbox, and Salesforce

Maximum sub sequence sum in an array
Use Kadane's algorithm
Initialize max_so_far and max_ending_here to 0
Iterate through the array and update max_ending_here and max_so_far
Return max_so_far
Endianness refers to the byte order of a system. It determines how multi-byte data types are stored in memory.
Little-endian systems store the least significant byte first, while big-endian systems store the most significant byte first.
Endianness can affect the way data is transmitted between systems.
To determine the endianness of a system, you can use the byte order mark (BOM) or write a test program that checks the by...
Sort an array of 0's and 1's only.
Use two pointers, one at the beginning and one at the end of the array.
Swap 0's from the beginning with 1's from the end until the pointers meet.
Alternatively, use a counting sort algorithm to count the number of 0's and 1's and then reconstruct the array.
Heaps are data structures used to efficiently find the maximum or minimum element in a collection.
Max heap: parent nodes are always greater than or equal to child nodes
Min heap: parent nodes are always smaller than or equal to child nodes
Heaps are commonly used in priority queues and sorting algorithms
Heap operations include insert, delete, and extract max/min
Example: An array [3, 8, 2, 5, 1, 4, 6] can be represented a
Find 3 numbers in an array where a+b=c.
Loop through the array and check for all possible combinations of a and b.
Use a hash table to store the values of a and b, and check if c is present in the hash table.
Sort the array and use two pointers to find a and b, and then check if their sum equals c.
Algorithms for manipulating arrays and strings in coding
Use sorting algorithms like quicksort and mergesort for arrays
Use string manipulation functions like substring and replace for strings
Use dynamic programming for optimizing solutions to array and string problems

Cyber security is the practice of protecting systems, networks, and data from digital attacks.
Cyber security involves implementing measures to prevent unauthorized access, data breaches, and other cyber threats.
It includes technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, damage, or unauthorized access.
Examples of cyber security measures include firewalls, ant...
Types of encryption include symmetric encryption, asymmetric encryption, and hashing.
Symmetric encryption: Uses the same key for both encryption and decryption, examples include AES and DES.
Asymmetric encryption: Uses a pair of public and private keys for encryption and decryption, examples include RSA and ECC.
Hashing: Converts data into a fixed-size string of bytes, examples include MD5 and SHA.

To debug the slow behavior of the API, analyze network latency, check for database issues, monitor server performance, and review code for potential bottlenecks.
Analyze network latency to identify any issues with data transmission.
Check for database issues such as slow queries or insufficient indexing.
Monitor server performance to ensure it has enough resources and is not overloaded.
Review the code for potential bottle...
