10+ RDC Concrete (India) Interview Questions and Answers

Clustering groups data points based on similarity while classification assigns labels to data points based on predefined categories.

• Clustering is unsupervised learning while classification is supervised learning.

• Clustering is used to find patterns in data while classification is used to predict the category of a data point.

• Examples of clustering algorithms include k-means and hierarchical clustering while examples of classification algorithms include decision trees and logist...read more

I would like to create a program that generates a random password.

• Use a combination of letters, numbers, and special characters

• Allow the user to specify the length of the password

• Ensure that the password is strong and not easily guessable

SOLID principles are a set of five design principles in object-oriented programming to make software designs more understandable, flexible, and maintainable.

• S - Single Responsibility Principle: A class should have only one reason to change.

• O - Open/Closed Principle: Software entities should be open for extension but closed for modification.

• L - Liskov Substitution Principle: Objects of a superclass should be replaceable with objects of its subclasses without affecting the func...read more

Content hugging is a constraint used in Auto Layout to determine how much a view resists growing beyond its intrinsic content size.

• Content hugging priority is a value between 1 and 1000, with higher values indicating a stronger resistance to growing.

• Views with higher content hugging priorities will try to maintain their intrinsic content size rather than expand to fill available space.

• Content hugging is often used in conjunction with content compression resistance to define h...read more

Binary search is a divide and conquer algorithm that finds the position of a target value within a sorted array.

• Start by defining the low and high indices of the array.

• Calculate the middle index and compare the target value with the middle element.

• If the target value is less than the middle element, update the high index to mid-1.

• If the target value is greater than the middle element, update the low index to mid+1.

• Repeat the process until the target value is found or the low ...read more

Oops concept is a programming paradigm that focuses on objects and classes to organize code and promote reusability.

• Oops stands for Object-Oriented Programming

• Key concepts include classes, objects, inheritance, polymorphism, and encapsulation

• Classes are blueprints for objects, defining their properties and behaviors

• Objects are instances of classes, representing real-world entities

• Inheritance allows classes to inherit properties and behaviors from other classes

• Polymorphism ena...read more

Auto layout is a constraint-based layout system used in iOS and macOS development to create user interfaces that adapt to different screen sizes and orientations.

• Auto layout allows developers to create flexible and adaptive user interfaces by defining relationships between UI elements.

• Constraints are used to specify the position and size of UI elements relative to each other or to the parent view.

• Auto layout automatically adjusts the layout of UI elements based on the availab...read more
