Check whether two strings are anagram of each other
Difficulty Level : Easy
Last Updated : 03 Jan, 2022
 
Write a function to check whether two given strings are anagram of each other or not. An anagram of a string is another string that contains the same characters, only the order of characters can be different. For example, “abcd” and “dabc” are an anagram of each other.

Method 1 (Use Sorting)  

Sort both strings
Compare the sorted strings
Below is the implementation of the above idea:






















// C++ program to check whether two strings are anagrams
// of each other
#include <bits/stdc++.h>
using namespace std;

/* function to check whether two strings are anagram of
each other */
bool areAnagram(string str1, string str2)
{
	// Get lengths of both strings
	int n1 = str1.length();
	int n2 = str2.length();

	// If length of both strings is not same, then they
	// cannot be anagram
	if (n1 != n2)
		return false;

	// Sort both the strings
	sort(str1.begin(), str1.end());
	sort(str2.begin(), str2.end());

	// Compare sorted strings
	for (int i = 0; i < n1; i++)
		if (str1[i] != str2[i])
			return false;

	return true;
}

// Driver code
int main()
{
	string str1 = "test";
	string str2 = "ttew";

	// Function Call
	if (areAnagram(str1, str2))
		cout << "The two strings are anagram of each other";
	else
		cout << "The two strings are not anagram of each "
				"other";

	return 0;
}
