Question

How to print the characters need to be removed so that two strings become anagram in Scala

Answer 1

import scala.collection.mutable

def printCharactersNeedToBeRemovedForAnagram(str1: String, str2: String): Unit = {
  val charCounts = mutable.Map[Char, Int]().withDefaultValue(0)

  // Count character frequencies in both strings
  (str1 + str2).foreach { ch =>
    charCounts(ch) += 1
  }

  // Print characters with odd counts (not forming pairs)
  charCounts.foreach { case (ch, count) =>
    if (count % 2 != 0) {
      printf("%c ", ch)
    }
  }
}

val str1 = "masterfx"
val str2 = "ksampret"

printCharactersNeedToBeRemovedForAnagram(str1, str2)
