Dynamic memory management is a technique in which storage units are allocated based on the requirements continuously. Using dynamic memory allocations, individual data structures can be either stored separately or combined to form entities called composites. These composites can be worked on when required...

They are also important for heap sorting, which is a method of organizing data efficiently. A min-heap is where all the parent nodes are smaller than the children—image by Author. Intermediate Data Structures Interview Questions Having covered the basics, let's move on to some intermediate-...
17) Are linked lists considered linear or non-linear data structures? A linked list is consideredboth linear and non-lineardata structure depending on the situation. On the basis ofdata storage, it is considered as non-linear data structure. On the basis ofaccess strategy, it is considered as...
10) Which data structures are applied when dealing with a recursive function? Recursion, is a function that calls itself based on a terminating condition, makes use of the stack. Using LIFO, a call to a recursive function saves the return address so that it knows how to return to the call...
String response = given().when().get("/api").asString(); JsonPath jsonPath = new JsonPath(response); String value = jsonPath.getString("data[0].name"); // Extracts the name from the first element in a data array. Handling Nested JSON Objects: For deeply nested structures, you can ch...
Whether you’re just getting into the data engineer job market or your interview is tomorrow, practice is an essential part of the interview preparation process for a data engineer. Data engineering interview questions assess your data engineering skills and domain expertise. They are based on a ...
17. How would you design a highly available and scalable system on the cloud? Points to Include: Use of multi-region setups to prevent downtime. Load balancing for even traffic distribution. Auto-scaling to match resource demand. Redundancy and regular backups for data reliability. ...
We start off by calling the algorithm on the given node and set that it's visited. We then check all of the node's neighbors, and for each one, run the same algorithm if it isn't visited. This means that before advancing to the next neighbor, it visits all of the children of the...
Persistence means storing data on the disk so that it can be retrieved without being altered the next time the app is opened. From simple to complex, there are the following methods for storing data: Data structures such as arrays, dictionaries, sets, and other data structures are perfect ...
