Remove key value from Map in Scala

The deletion of Scala map keys can be obtained by utilizing – operator. This operator is utilized to delete the set of keys of the map.
Syntax:

def -(elem1: A, elem2: A, elems: A*): Map[A, B]

It returns a new map containing all the elements of the given Map except the set of keys which are deleted using the above operator.
Example #1:

// Scala program of deleting
// keys

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating a map
        val m1 = Map("geeks" -> 5, "for" -> 3)

        // Applying - operator
        val result = m1.-("for")

        // Displays output
        println(result)

    }
}

Output:

Map(geeks -> 5)

In above example here for key is deleted.
Example #2:

// Scala program of deleting
// keys

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating a map
        val m1 = Map("geeks" -> 5, "for" -> 3, "cs" -> 2)

        // Applying - operator
        val result = m1.-("for", "geeks")

        // Displays output
        println(result)

    }
}

Output:

Map(cs -> 2)
