Last update on December 21 2024 10:26:49 (UTC/GMT +8 hours)

Write a Scala function to check if a given string is a palindrome.

Sample Solution:

Scala Code:

object PalindromeChecker {
  def isPalindrome(str: String): Boolean = {
    val reversed = str.reverse
    str == reversed
  }

  def main(args: Array[String]): Unit = {
    val input1 = "madam"
    val isPalindrome1 = isPalindrome(input1)
    println(s"$input1 is a palindrome: $isPalindrome1")

    val input2 = "scala"
    val isPalindrome2 = isPalindrome(input2)
    println(s"$input2 is a palindrome: $isPalindrome2")
  }
}

Sample Output:

madam is a palindrome: true
scala is a palindrome: false
