Scala Tuple: Swap tuple elements

Last update on December 21 2024 10:28:05 (UTC/GMT +8 hours)

Write a Scala program to swap the elements of a tuple (e.g., (100, 200) should become (200, 100)).

Sample Solution:

Scala Code:

object SwapTupleElementsExample {
  def main(args: Array[String]): Unit = {
    // Create a tuple
    val nums = (100, 200)
    println("Original Tuple: "+nums)
    // Swap the elements of the tuple
    val swappedTuple = nums.swap

    // Print the swapped tuple
    println("Swapped tuple: " + swappedTuple)
  }
}

Sample Output:

Original Tuple: (100,200)
Swapped tuple: (200,100)

Explanation:

In the above exercise -

• First, we create a tuple "nums" with elements 1 and 2.
• To swap the tuple elements, we use the swap method, which returns a new tuple with the elements swapped.
• We assign the resulting swapped tuple to the variable swappedTuple.
• Finally, we print the swapped tuple using println.
