4 min readTo feed a nested collection in Kotlin, you can follow these steps:Declare a nested collection variable that you want to populate. For example: val nestedList: MutableList<MutableList<Int>> = mutableListOf() Here, we have created a nested list of type MutableList<MutableList<Int>>.Use the add method to append elements to the nested collection. Start by creating the inner collection using the mutableListOf() function.

9 min readIn Kotlin, generics are used to create reusable code that can work with different types of data. When generics are specified as "int" in Kotlin, it means that the code is designed to work specifically with integers.Generics allow you to define classes, functions, or interfaces that can operate on different types of data without sacrificing type safety.

3 min readGenerating random numbers in MATLAB is simple and can be done using several built-in functions. The most commonly used functions are:rand: This function generates a random number between 0 and 1 from a uniform distribution. It takes no input arguments and returns a single random number or an array of random numbers.

6 min readIn Kotlin, it is not possible to directly return two values from a function like in some programming languages. However, there are a few different approaches to achieve the same result:Using Pairs: Kotlin provides the Pair class to hold two values. You can create a Pair object and return it from the function.

8 min readArrays in MATLAB are fundamental data structures that allow the storage and manipulation of collections of values. An array is defined as a variable that can hold multiple elements of the same data type. In MATLAB, arrays can be created and manipulated using various methods.Creating arrays:One way to create an array is by manually entering the elements enclosed in square brackets ([]). For example, to create a 1-dimensional array, you can use the syntax: array = [1, 2, 3, 4, 5].

7 min readTo test a private function in Kotlin, you can follow these steps:Import the necessary testing dependencies: Depending on your build tool, you need to add the appropriate testing framework in your project, such as JUnit or KotlinTest. Create a new test class: Create a separate test class file that corresponds to the file containing the private function you want to test. Use reflection: Kotlin does not provide direct access to private functions.
