Sum of the alphabetical values of the characters of a string

  • Difficulty Level : Medium
  • Last Updated : 19 Mar, 2021

You are given an array of strings str, the task is to find the score of a given string s from the array. The score of a string is defined as the product of the sum of its characters’s alphabetical values with the position of the string in the array.
Examples: 
 

Input: str[] = {“sahil”, “shashanak”, “sanjit”, “abhinav”, “mohit”}, s = “abhinav” 
Output: 228 
Sum of alphabetical values of “abhinav” = 1 + 2 + 8 + 9 + 14 + 1 + 22 = 57 
Position of “abhinav” in str is 4, 57 x 4 = 228 
Input: str[] = {“geeksforgeeks”, “algorithms”, “stack”}, s = “algorithms” 
Output: 244 
 

 

Approach: 
 

  • Find the given string in the array and store the position of the string.
  • Then calculate the sum of the alphabetical values of the given string.
  • Multiply the position of the string in the given array with the value calculated in the previous step and print the result.

Below is the implementation of the above approach: 
 

C++




// C++ implementation of the approach
#include <bits/stdc++.h>
using namespace std;
 
// Function to find string score
int strScore(string str[], string s, int n)
{
    int score = 0, index;
    for (int i = 0; i < n; i++) {
        if (str[i] == s) {
            for (int j = 0; j < s.length(); j++)
                score += s[j] - 'a' + 1;
            index = i + 1;
            break;
        }
    }
 
    score = score * index;
    return score;
}
 
// Driver code
int main()
{
    string str[] = { "sahil", "shashanak"
                      , "sanjit", "abhinav", "mohit" };
    string s = "abhinav";
    int n = sizeof(str) / sizeof(str[0]);
    int score = strScore(str, s, n);
    cout << score << endl;
 
    return 0;
}

Java




//  Java implementation of the approach
import java.io.*;
 
class GFG {
 
 
// Function to find string score
static int strScore(String str[], String s, int n)
{
    int score = 0, index=0;
    for (int i = 0; i < n; i++) {
        if (str[i] == s) {
            for (int j = 0; j < s.length(); j++)
                score += s.charAt(j) - 'a' + 1;
            index = i + 1;
            break;
        }
    }
 
    score = score * index;
    return score;
}
 
// Driver code
 
 
    public static void main (String[] args) {
            String str[] = { "sahil", "shashanak"
                    , "sanjit", "abhinav", "mohit" };
    String s = "abhinav";
    int n = str.length;
    int score = strScore(str, s, n);
    System.out.println( score);
    }
}

        if (str[i] == s):
            for j in range(len(s)):
                score += (ord(s[j]) -
                          ord('a') + 1)
            index = i + 1
            break
    score = score * index
    return score

str = ["sahil", "shashanak", "sanjit",
                  "abhinav", "mohit" ]
