Hashing is a technique that takes data of any size and turns it into a fixed-size value called a hash value using a hash function. One common use of hashing is in hash tables, where it helps match keys with specific locations in an array, making it easy to find and retrieve data qu...

Hashing Static Hashing Dynamic Hashing NoneAnswer: A) HashingExplanation:By using the hashing algorithm, it is possible to find a data record directly on the disk without the need for an index.Discuss this Question 3. A hashing function is used to generate the ___ of the data blocks in ...
Here while rehashing process, there are chances to generate the cyclic dependency where one element in linked list [in any bucket] can point to any previous node in same bucket. This will result in infinite loop, because rehashing code contains a “while(true) { //get next node; }” bl...
Active sniffing: Sniffing in a point-to-point network device called the switch is referred to as active sniffing. The switch is responsible for the regulation of the data flow between its ports. This is done through the active monitoring of the MAC address on each port, which enables the pa...
A miner or a group of miners attempting to control more than 50% of a network’s hashing capacity, processing power, or hash rate is known as a 51 percent attack on a blockchain network. The attacker may prevent new transactions from taking place or being verified in this attack. They ...
Hashmaps, also known as hashtables, represent one of the most common implementations of hashing. Hashmaps stores key-value pairs (e.g., employee ID and employee name) in a list that is accessible through its index. We could say that a hashmap is a data structure that leverages hashing...
Flip adjacent bits, then flip adjacent 2 bit sets, then 4-bits and so on. Each of this swap can be done in constant time using appropriate masks and shifts. if (a+b) < a or (a+b) < b then overflow has occurred Data structures and algorithms questions ...
Node JS Developer Interview Questions About Asynchronous Programming focus on the basics of callbacks and simple asynchronous code patterns for entry-level positions, advanced positions require in-depth knowledge of Promises, async/await, and the event loop intricacies. A strong grasp of asynchronous ...
“. I will leave, how hashmap works, part on you to read from linked post, but in summary it works on principle of Hashing. Key’s hash code is used primarily in conjunction to its equals() method, for putting a key in map and then searching it back from map. So if hash code ...
