finding if two words are anagrams of each other

Question

I am looking for a method to find if two strings are anagrams of one another.

Ex: string1 - abcde
string2 - abced
Ans = true
Ex: string1 - abcde
string2 - ab         


        

Answer 1

How about Xor'ing both the strings??? This will definitely be of O(n)

char* arr1="ab cde";
int n1=strlen(arr1);
char* arr2="edcb a";
int n2=strlen(arr2);
// to check for anagram;
int c=0;
int i=0, j=0;   
if(n1!=n2) 
  printf("\nNot anagram");
else {
   while(i

}
