This program sorts an array of strings in alphabetical order using a simple sorting algorithm.
Use built-in sorting functions like `sort()` in Python: `arr.sort()` or `sorted(arr)`.
Implement a sorting algorithm like Bubble Sort: repeatedly swap adjacent elements if they are in the wrong order.
Example of Bubble Sort: For array ['banana', 'apple', 'cherry'], after sorting it becomes ['apple', 'banana', 'cherry'].

What people are saying about TCS
Explanation of static keywords, methods, and variables with examples.
Static keyword is used to declare a variable or method that belongs to the class rather than an instance of the class.

Static methods can be called without creating an instance of the class.
Example: public static int count = 0; // static variable
Example: public static void printMessage()...
OOP (Object-Oriented Programming) is a programming paradigm based on objects and classes, promoting code reusability and organization.
Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).
Inheritance: Mechanism to create a new class using properties and methods of an existing class (e.g., a 'Dog' class inheriting from an 'Animal' class).
Polymorphism: Ability to present t...

Testing types refer to different approaches and techniques used to validate software functionality.
Unit Testing: Testing individual components or modules of the software.
Integration Testing: Testing how different modules work together.
System Testing: Testing the entire system as a whole.
Acceptance Testing: Testing to ensure the software meets the requirements of the end users.
Performance Testing: Testing the perfo...
Some difficulties faced in automation include handling dynamic elements, synchronization issues, and maintenance of test scripts.
Handling dynamic elements on the webpage can be challenging as they may change frequently.
Synchronization issues between the automation tool and the application can lead to test failures.
Maintenance of test scripts becomes difficult as the application evolves and changes over time.
Webdriver Waits are used to wait for a certain condition to occur before proceeding with the next command.
Webdriver Waits are used to handle synchronization issues in test automation.
There are three types of waits: Implicit, Explicit, and Fluent.
Commands like 'elementToBeClickable', 'visibilityOf', and 'titleContains' are used with waits.
Example: WebDriverWait wait = new WebDriverWait(driver, 10); wait.until(Expec...
