Two strings, a and b, are called anagrams if they contain all the same characters in the same frequencies. For this challenge, the test is not case-sensitive. For example, the anagrams of CAT are CAT, ACT, tac, TCA, aTC, and CtA.
Function Description
Complete the isAnagram function in the editor.
isAnagram has the following parameters:
- string a: the first string
- string b: the second string
Returns
- boolean: If a and b are case-insensitive anagrams, return true. Otherwise, return false.
Input Format
The first line contains a string a.
The second line contains a string b.
Constraints
- 1 ≤ length(a), length(b) ≤ 50
- Strings a and b consist of English alphabetic characters.
- The comparison should NOT be case sensitive.
Sample Input 0
anagram
margana
Sample Output 0
Anagrams
Explanation 0
| Character | Frequency: anagram | Frequency: margana |
|---|---|---|
A or a | 3 | 3 |
G or g | 1 | 1 |
N or n | 1 | 1 |
M or m | 1 | 1 |
R or r | 1 | 1 |
The two strings contain all the same letters in the same frequencies, so we print “Anagrams”.
Sample Input 1
anagramm
marganaa
Sample Output 1
Not Anagrams
Explanation 1
| Character | Frequency: anagramm | Frequency: marganaa |
|---|---|---|
A or a | 3 | 4 |
G or g | 1 | 1 |
N or n | 1 | 1 |
M or m | 2 | 1 |
R or r | 1 | 1 |
The two strings don’t contain the same number of a‘s and m‘s, so we print “Not Anagrams”.
Sample Input 2
Hello
hello
Sample Output 2
Anagrams
Explanation 2
| Character | Frequency: Hello | Frequency: hello |
|---|---|---|
E or e | 1 | 1 |
H or h | 1 | 1 |
L or l | 2 | 2 |
O or o | 1 | 1 |
The two strings contain all the same letters in the same frequencies, so we print “Anagrams”.
Solution Implementation
import java.util.Scanner;

char a_string[]=a.toLowerCase().toCharArray();
char b_string[]=b.toLowerCase().toCharArray();
boolean returnValue;
if(a_string !=null && b_string!=null){
java.util.Arrays.sort(a_string);
java.util.Arrays.sort(b_string);
returnValue=java.util.Arrays.equals(a_string,b_string);
return returnValue;
}
else{
return returnValue=false;
}
}
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String a = scan.next();
String b = scan.next();
scan.close();
boolean ret = isAnagram(a, b);
System.out.println( (ret) ? "Anagrams" : "Not Anagrams" );
}
