• Once the stack is empty, push the elements back in reverse order using recursion.

• Ensure to handle base cases like empty stack or single element stack.

• Example: If the input stack is [1, 2, 3], after reversal it should be [3, 2, 1].

Q5. What is meant by normalization and denormalization?
Ans. 
Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. Denormalization is the opposite process.
• Normalization involves breaking down a table into smaller tables and defining relationships between them to reduce redundancy.

• Denormalization involves combining tables to reduce the number of joins needed for queries, sacrificing some normalization benefits for performan...read more

In this round, the interviewer asked questions related to my projects. Since I did some web development projects , the interviewer grilled me on concepts related to HTML , CSS and JavaScript.

Q1. How do you compare an Object and a Map in JavaScript?

• Objects are unordered collections of key-value pairs, while Maps maintain the order of insertion.

• Maps allow any type of key, while Objects only allow strings and symbols as keys.

• Maps have better performance for scenarios involving frequent additions and removals of key-value pairs.

• Objects hav...read more

Q2. What is the difference between 'let' and 'var' in JavaScript?
Ans. 
let is block-scoped while var is function-scoped in JavaScript.
• let is block-scoped, meaning it is only accessible within the block it is declared in.

• var is function-scoped, meaning it is accessible throughout the function it is declared in.

• Using let can help prevent variable hoisting issues.

• let allows for better control over variable scope and reduces the risk of unintended variable redeclarations.
