- What is data structure?
Definition, storage, and retrieval of data using a structured and systematic framework is what data structure is all about. Different types of data can be stored in a data structure.
- What are various data structures available?
The commonly used data structures include lists, arrays, stacks, queues, graphs, trees, etc.
- What is linear data structure?
Linear data structures have sequentially arranged data elements. Lists and arrays are examples of linear data structures.
- What are common operations that can be performed on a data structure?
The five common operations performed on any data structure are the following: Insertion, Deletion, Traversal, Searching, and Sorting.
- What is a linked list?
In a linked list, the items in the list are linked through links, which can be either pointers or references.
- What are stacks?
Stacks are Abstract Data Types used to hold and retrieve values in the Last In First Out order in data structures.
- What is an array?
An array is a container for storing a fixed number of items, and the items inside should also be the same type.
- What is an algorithm?
Algorithms are sets of ordered steps that, when executed, solve problems.
- Which method can be used to add items from another set to the current set?
To add items from another set into the current set, the update() method can be used.
- Which method can be used to remove an item from a list?
There are at least three ways to remove elements from a list: using the remove() method, using the pop() method, or using the del operator.
A data structure is nothing but a specialized way of organizing and storing data in a computer system. This allows for more efficient ways of handling data as compared to storing data just sequentially. With the help of data structures and algorithms, we can better understand the nature of a problem and arrive at an optimum solution.

Once you’ve built a complete skills assessment, inviting candidates is easy. Sit back and wait for the results to come in, and send reminders if you need to.
The main challenge while hiring quality developers will always be to differentiate between good developers and expert developers. The inherent bias involved in traditional, CV-based hiring practices is another challenge recruiters face.
Surveys suggest recruiting developers with the right skills will be one of the biggest business challenges in 2022. In this case, skills-based hiring is the best solution that organizations can adopt.
TestGorilla offers you world-class, pre-employment assessments to vet candidates effectively. Our data-driven approach provides you with greater insight into a candidate’s ability. Don’t let the CV speak for your candidates anymore. Save valuable time by letting our assessments do the hard work for you.
