Sort an array of strings containing both letters and numbers, with letters on the left and numbers on the right.

• Create two separate arrays for letters and numbers

• Iterate through the original array and separate letters and numbers into their respective arrays

• Combine the two arrays with letters first and numbers next

Destructive testing of concrete specimens involves various types of tests to assess the strength and durability of the concrete.

• Compression test: Measures the maximum load a concrete specimen can bear before failure.

• Splitting tensile test: Evaluates the tensile strength of concrete by applying a diametrical load.

• Flexural test: Determines the flexural strength of concrete by subjecting a beam specimen to bending.

• Abrasion test: Assesses the resistance of concrete to wear and er...read more

Non Destructive Testing (NDT) methods for concrete members include ultrasonic testing, rebound hammer test, and ground penetrating radar.

• Ultrasonic testing is used to measure the thickness of concrete, detect voids, and assess the quality of concrete.

• Rebound hammer test is used to determine the compressive strength of concrete by measuring the rebound of a spring-loaded hammer.

• Ground penetrating radar (GPR) is used to detect embedded objects, such as reinforcement bars or voi...read more

To cut a cake into 8 pieces with 3 cuts, make two perpendicular cuts through the center of the cake.

• Make the first cut horizontally through the center of the cake, dividing it into two equal halves.

• Make the second cut vertically through the center of the cake, dividing it into four quarters.

• Make the third cut horizontally through the center of the cake, dividing it into eight equal pieces.

Our framework is a hybrid framework combining data-driven and keyword-driven approaches for efficient and scalable testing.

• Combines data-driven and keyword-driven testing

• Allows for reusable test scripts and data separation

• Supports automation of test cases with minimal coding

• Enhances test coverage and scalability

• Example: Using Excel sheets for test data and keywords for test actions

Project frameworks are structures that provide guidelines and best practices for managing projects.

• Waterfall model

• Agile framework

• Scrum methodology

• Kanban method

• Lean approach

We utilize various classes while coding to organize and structure our code.

• Classes help in organizing code into logical units

• Classes can be used for creating objects with properties and methods

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

• Examples: String, Integer, List, HashMap

Retesting is testing the same functionality again to ensure the defect is fixed, while regression testing is testing the unchanged parts of the software to ensure new changes haven't affected them.

• Retesting is done to confirm that a specific defect has been fixed, while regression testing is done to ensure that new changes have not affected the existing functionality.

• Retesting focuses on the defect fixes, while regression testing focuses on the unchanged parts of the software...read more

Data types are classifications of data items that tell the compiler or interpreter how the programmer intends to use the data.

• Primitive data types: int, float, double, char, boolean

• Non-primitive data types: arrays, classes, interfaces

• Derived data types: pointers, references

Software development life cycle is a process used by software development teams to design, develop, test, and deploy software applications.

• SDLC consists of several phases including planning, analysis, design, implementation, testing, and maintenance.

• Each phase has its own set of activities and deliverables that contribute to the overall success of the project.

• Examples of SDLC models include Waterfall, Agile, and DevOps, each with its own approach to software development.

• Testi...read more

Software testing life cycle involves planning, designing, executing, and reporting on tests to ensure quality software.

• Planning phase involves defining test objectives, scope, and strategy.

• Design phase includes creating test cases, test data, and test environment setup.

• Execution phase involves running tests, recording results, and analyzing defects.

• Reporting phase includes documenting test results, defects, and overall quality assessment.
