    Which of the following are examples of software development tools?

    • Debuggers

    • Editors

    • Assemblers, compilers, and interpreters

    • All of the mentioned

    Correct Answer
    A. All of the mentioned
    Explanation
    All of the mentioned options, including debuggers, editors, and assemblers, compilers, and interpreters, are examples of software development tools. Debuggers help in identifying and fixing errors in the code, editors are used for writing and modifying code, and assemblers, compilers, and interpreters are used to convert high-level programming languages into machine code. Therefore, all of these tools play a crucial role in the software development process.

    How are the new states generated in the genetic algorithm?

    • Composition

    • Mutation

    • Cross-over

    • Both Mutation & Cross-over

    Correct Answer
    A. Both Mutation & Cross-over
    Explanation
    In the genetic algorithm, new states are generated through both mutation and cross-over. Mutation involves randomly changing the values of certain genes in an individual's chromosome, introducing new genetic material. Cross-over, on the other hand, involves combining genetic material from two parent individuals to create offspring with a mix of their genes. Both processes contribute to the generation of new states in the genetic algorithm, allowing for exploration of different solutions and increasing the diversity of the population.

    The __________ feature of MS Excel quickly completes a series of data.

    • Autocomplete

    • Autofill

    • Fill handle

    • Sorting

    Correct Answer
    A. Autofill
    Explanation
    Autofill is the correct answer because it is a feature in MS Excel that allows users to quickly complete a series of data by automatically filling in the remaining values based on the pattern established by the user. This feature is useful for tasks such as filling in a sequence of numbers or dates, saving time and effort.

    What is the complex system of structured messages?

    • Languages

    • Words

    • Signs

    • Speech

    Correct Answer
    A. Languages
    Explanation
    Languages are the complex system of structured messages. They consist of a set of rules and conventions that allow people to communicate and convey meaning through spoken, written, or signed words. Languages provide a framework for organizing and expressing thoughts, ideas, and information, making them an essential tool for human communication and understanding.

    Which is the first AI programming language?

    • BASIC

    • FORTRAN

    • IPL(Inductive logic programming)

    • LISP

    Correct Answer
    A. LISP
    Explanation
    LISP is considered to be the first AI programming language. It was developed in the late 1950s by John McCarthy and was specifically designed for artificial intelligence research. LISP stands for "LISt Processing" and is known for its ability to manipulate symbolic expressions and its support for recursion, which are essential features for AI programming. LISP has been widely used in various AI applications and has had a significant impact on the development of the field.

      Which of the following function is used for loading flat files?

    • read.data

    • Read.sheet

    • read.table

    • None of the mentioned

    Correct Answer
    A. read.table
    Explanation
    The function "read.table" is used for loading flat files. This function reads a file in table format and creates a data frame from it. It is commonly used for reading data from text files with a fixed number of columns. The function automatically detects the delimiter used in the file and can handle various types of file formats, such as CSV, TSV, or space-delimited files.

    Rate this question:

  • 8. 

    Which of the following algorithm in an online search algorithm?

    • Breadth-first search algorithm

    • Depth-first search algorithm

    • Hill-climbing search algorithm

    • None of the mentioned

    Correct Answer
    A. Hill-climbing search algorithm
    Explanation
    The Hill-climbing search algorithm is an online search algorithm because it continuously evaluates and selects the best available option at each step based on a heuristic evaluation function. It does not require the complete search space to be known in advance and can make decisions based on the current state of the search. This makes it suitable for online search scenarios where the search space is dynamic and changing.

  • 9. 

    Which of the following function is used for casting data frames?

    • Dcast

    • Ucast

    • Rcast

    • all of the mentioned

    Correct Answer
    A. Dcast
    Explanation
    The correct answer is dcast. The dcast function is used for casting data frames. Casting refers to the process of transforming the structure or format of data. In this case, dcast is specifically used to transform data frames into a different shape or format, typically by reshaping the data from long to wide format.

    Which of the following function is used for quantiles of quantitative values?

    • quantile

    • quantity

    • quantiles

    • all of the mentioned

    Correct Answer
    A. quantile
    Explanation
    The function "quantile" is used for calculating quantiles of quantitative values. Quantiles are values that divide a dataset into equal-sized subsets, representing the relative position of a particular value within the dataset. The "quantile" function allows us to determine these quantiles, which are useful for analyzing and understanding the distribution of data.

    Rate this question:

  • 11. 

    Point out the correct statement.

    • Head function work on string

    • Tail function work on string

    • The Head function works on the string, but the tail function does not.

    • None of the mentioned

    Correct Answer
    A. None of the mentioned
    Explanation
    The correct answer is "None of the mentioned" because none of the statements provided accurately describe the behavior of the head and tail functions. The head function typically returns the first element of a list or string, while the tail function returns all elements except the first. Therefore, these functions do not specifically work on strings alone.

    Rate this question:

  • 12. 

    Mutate function is used for casting as multi-dimensional arrays.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The mutate function is not used for casting as multi-dimensional arrays. It is used for making changes or modifications to an existing array or object. Casting as multi-dimensional arrays is typically done using other methods or functions specific to the programming language being used.

    Rate this question:

  • 13. 

    When a top-level function is entered, the LISP processor does...

    • It reads the function entered.

    • It prints the result returned by the function.

    • Large memory and high-speed processor.

    • All of the mentioned

    Correct Answer
    A. It prints the result returned by the function.
    Explanation
    When a top-level function is entered, the LISP processor prints the result returned by the function. This means that when the function is executed, the LISP processor will display the output of the function on the screen. This allows the user to see the result of the function and verify that it is correct.
