- Q1. What is polymorphism
- Ans.
Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
It enables a single interface to be used for different data types or classes.
Examples include method overloading and method overriding in object-oriented programming.
- Q2. Find missing number from nth number array.
- Ans.
Find missing number from nth number array.
Iterate through the array and calculate the sum of all numbers
Calculate the sum of numbers from 1 to n using the formula n*(n+1)/2
Subtract the sum of array from the sum of numbers from 1 to n to find the missing number
- Q3. Explain inheritance and it types
- Ans.
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
Inheritance allows a class to reuse code from another class.
Types of inheritance include single inheritance, where a class inherits from only one parent class, and multiple inheritance, where a class inherits from multiple parent classes.
