Scala Program: Remove an element from a set

Scala Set Exercise-7 with Solution

Write a Scala program to remove an element from a set.

Sample Solution:

Scala Code:

object SetElementRemovalExample {
  def main(args: Array[String]): Unit = {
    // Create a set
    val nums = Set(1, 2, 3, 4)

    // Print the initial set
    println("Initial Set: " + nums)

    // Remove an element from the set
    val element = 3
    val updatedSet = nums - element

    // Print the updated set
    println("Updated Set: " + updatedSet)
  }
}

Sample Output:

Initial Set: Set(1, 2, 3, 4)
Updated Set: Set(1, 2, 4)

Explanation:

In the above exercise,

• First, we create an immutable set "nums" containing 1, 2, 3, and 4.
• To remove an element from the set, we use the - operator. We specify the element to remove from the set.
• In the program, we remove element 3 from the set by using the line val updatedSet = nums - element. This creates a new set updatedSet that does not include element 3.
• Finally, we print the initial set before removal and the updated set after removal.
