TCS iON Junior Software Developer Interview Questions, Process, and Tips

An array is a data structure that stores a collection of elements of the same type in a contiguous block of memory.

• Arrays can be accessed using an index starting from 0.

• They have a fixed size, which is determined at the time of declaration.

• Arrays can store elements of any data type, including strings.

• Example: ['apple', 'banana', 'orange']

Different types of queues include linear, circular, priority, and double-ended.

• Linear queue follows a First-In-First-Out (FIFO) order.

• Circular queue is similar to linear queue but the last element points to the first element.

• Priority queue assigns a priority to each element and dequeues the highest priority element first.

• Double-ended queue allows insertion and deletion at both ends.

OOP is a programming paradigm that uses objects to represent real-world entities. Project details can be explained using OOP concepts.

• OOP is based on the concept of classes and objects

• Classes are like blueprints for objects

• Objects have properties and methods

• Encapsulation, inheritance, and polymorphism are key OOP concepts

• Example: A car class can have properties like make, model, and year, and methods like start and sto

To stop async code based on specification condition, use cancellation tokens.

• Use CancellationTokenSource to create a cancellation token

• Pass the cancellation token to the async method

• Check the cancellation token in the async method using ThrowIfCancellationRequested()

• Cancel the token when the specification condition is met

Swapping array elements and reversing string using recursion.

• Create a recursive function that swaps the first and last elements of the array until the middle is reached.

• Create a recursive function that reverses the string by swapping the first and last characters until the middle is reached.

• Use a temporary variable to store the value of the element being swapped.

• Make sure to handle edge cases such as empty arrays or st
