My issue

I can’t figure out why this is giving wrong output.
I created a frequency array which checks frequency of all alphabets present in the string. If freq of any alphabet is 0 than the price of that alphabet gets added to the sum.

My code

#include<bits/stdc++.h> 
#include <iostream>
using namespace std;

int main() {
    int t; cin>>t ;
    
    while(t--){
        char array[26] ;
        for(int i = 0 ; i<26 ; i++){
            cin>>array[i] ;
        }
        
        string str ; cin>>str ;
        
        int freq[26]= {0} ;
        
        for(int i = 0; i<str.length() ; i++){
            int temp;
            temp = int(str[i]) - 97 ;
            
            freq[temp] ++ ;
        }
        
        int sum = 0 ;
        
        for(int i = 0 ; i< 26 ; i++){
            if(freq[i] == 0){
                sum= sum + array[i] ;
            }
        }
        
        
        cout<<sum<<endl ;
    }
	return 0;
}

@shylamadan
Instead of integer array of size 26 u have made char array of size 26 to take the price inputs for the alphabets.
