Question

How to check if two strings are anagram (same letters different words) in C++

Answer 1

#include <bits/stdc++.h> 

using namespace std; 
  
bool isAnagram(string s1, string s2) { 
    int lens1 = s1.length(); 
    int lens2 = s2.length(); 
  
    if (lens1 != lens2) 
        return false; 
  
    sort(s1.begin(), s1.end()); 
    sort(s2.begin(), s2.end()); 

    for (int i = 0; i < lens1; i++) 
        if (s1[i] != s2[i]) 
            return false; 
  
    return true; 
} 
  
int main() 
{ 
    string s1 = "main"; 
    string s2 = "niam"; 

    if (isAnagram(s1, s2)) {
        cout << "Anagram"; 
    }
    else {
        cout << "Not Anagram"; 
    }
  
    return 0; 
} 


/*
run:

Anagram

*/
