Find lowest and highest number in an array efficiently

• Use a loop to iterate through the array and keep track of the lowest and highest numbers

• Initialize variables for lowest and highest numbers with the first element of the array

• Compare each element with the current lowest and highest numbers and update accordingly

Resistance is the opposition to the flow of electric current in a circuit.

• Resistance is a property of a material or component that hinders the flow of electric current.

• It is measured in ohms (Ω) and is denoted by the symbol 'R'.

• Resistance converts electrical energy into heat energy.

• Higher resistance leads to lower current flow and vice versa.

• Examples of resistors include light bulbs, heating elements, and electrical wires.

Constructors are special methods in a class that are used to initialize objects of that class.

• Constructors have the same name as the class they belong to.

• They are called automatically when an object is created.

• Constructors can have parameters to initialize object properties.

• Example: public class Car { public Car(String color) { this.color = color; }}

Implicit and explicit waits are used in Selenium to wait for elements to load. Xpath is a way to locate elements on a webpage.

• Implicit wait: waits for a certain amount of time before throwing an exception if the element is not found

• Explicit wait: waits for a certain condition to be met before proceeding with the code

• Xpath: a way to locate elements on a webpage using the path of the element in the HTML structure

• Python code: example - driver.implicitly_wait(10) waits for 10 sec...read more

Polymorphism is the ability of a single function or method to operate on different types of data.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.

• Example: A method that takes a superclass object as a parameter can also take a subclas...read more
