i guess you do not the the frequency array concept , see in all these frequencies problems what you need to do is just simply create an array of 26 elements initialized 0.

the simply iterate through the string.

for(i=0;i<s.length();i++)
arr[s[i]-'a']=1:

what this will do is whichever elements are present , for e.g if a is present then 0th pos off arr will be filled with 1 , and then you can just iterate through the array of 26 elements to check which elements are 0 , indicting that they are not present , simply calculate the sum.
sum=0

for (int i=0;i<26;i++)
{
if (a[i]==0)
sum+=s[i]
}

print sum
