Question

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

Answer 1

package main

import (
	"fmt"
	"math"
)

const TotalABCLetters = 26

func PrintCharactersNeedToBeRemovedForAnagram(str1, str2 string) {
	count1 := make([]int, TotalABCLetters)
	count2 := make([]int, TotalABCLetters)

	// count char frequency str1
	for _, ch := range str1 {
		count1[ch -'a']++
	}

	// count char frequency str2
	for _, ch := range str2 {
		count2[ch -'a']++
	}

	for i := 0; i < TotalABCLetters; i++ {
		if math.Abs(float64(count1[i] - count2[i])) > 0 {
			fmt.Printf("%c ", rune(i+'a'))
		}
	}
}

func main() {
	str1 := "masterfx"
	str2 := "ksampret"

	PrintCharactersNeedToBeRemovedForAnagram(str1, str2)
}
