Question

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

Answer 1

public class MyClass {
    private static void PrintCharactersNeedToBeRemovedForAnagram(String str1, String str2) {
        int TotalABCLetters = 26;
         
        int count1[] = new int[TotalABCLetters];
        int count2[] = new int[TotalABCLetters];
         
        int size1 = str1.length();
        int size2 = str2.length();
 
        // count char frequency str1
        for (int i = 0; i < size1; i++) {
            count1[str1.charAt(i) - 'a']++;
        }
     
        // count char frequency str2
        for (int i = 0; i < size2; i++) {
            count2[str2.charAt(i) - 'a']++;
        }
    
    	for (int i = 0; i < TotalABCLetters; i++) {
    		if (Math.abs(count1[i] - count2[i]) != 0) {
    			System.out.print((char)(i + 'a') + " ");
    		}
    	}
    }

    public static void main(String args[]) {
        String str1 = "masterfx";
	    String str2 = "ksampret";

	    PrintCharactersNeedToBeRemovedForAnagram(str1, str2);
    }
}
