So, if you thinking 'Who can write my scala assignment' or simply seeking clarity on challenging assignments, fret not – we've got you covered.

Question 1: Higher-Order Functions and Pattern Matching

Task:

Write a Scala function called `processList` that takes a list of integers and a function as arguments. The function `processList` should apply the given function to each element of the list and return a new list containing the results. Additionally, implement a case class called `Operation` with two fields: `name` of type String and `operation` of type `(Int, Int) = Int`, where `operation` is a function that takes two integers and returns an integer.

Solution:

```scala
// Define the case class Operation
case class Operation(name: String, operation: (Int, Int) = Int)

// Define the processList function
def processList(list: List[Int], func: Int = Int): List[Int] = {
  list.map(func)
}

// Sample usage
val numbers = List(1, 2, 3, 4, 5)
val increment = (x: Int) = x + 1
val incrementedNumbers = processList(numbers, increment)
println("Incremented numbers: " + incrementedNumbers)
```

Question 2: Implicit Parameters and Type Classes

Task:

Implement a generic `Converter` trait that converts a value of one type to another. Define an implicit object for converting `Double` values to `Int` values and another implicit object for converting `String` values to `Int` values. Test your implementation by converting a `Double` value and a `String` value to an `Int`.

Solution:

```scala
// Define the Converter trait
trait Converter[A, B] {
  def convert(value: A): B
}

// Define implicit object for converting Double to Int
implicit object DoubleToIntConverter extends Converter[Double, Int] {
  def convert(value: Double): Int = value.toInt
}

// Define implicit object for converting String to Int
implicit object StringToIntConverter extends Converter[String, Int] {
  def convert(value: String): Int = value.toInt
}

// Function to convert using implicit converter
def convert[A, B](value: A)(implicit converter: Converter[A, B]): B = {
  converter.convert(value)
}

// Test the conversion
val doubleValue: Double = 3.14
val stringIntValue: String = "42"
val convertedDouble: Int = convert(doubleValue)
val convertedStringInt: Int = convert(stringIntValue)
println("Converted Double: " + convertedDouble)
println("Converted String to Int: " + convertedStringInt)
```
