Cost to make a string Panagram in C++

C++Server Side ProgrammingProgramming

In this tutorial, we will be discussing a program to find the cost of making a string panagram.

For this we will be provided with an array of integers. Our task is to convert the given string into a panagram and calculate the cost of doing that with the help of the array provided with the costs of adding characters.

Example

 Live Demo

#include <bits/stdc++.h>
using namespace std;
//calculating the total cost of
//making panagram
int calc_cost(int arr[], string str) {
   int cost = 0;
   bool occurred[26] = { false };
   for (int i = 0; i < str.size(); i++)
      occurred[str[i] - 'a'] = true;
   for (int i = 0; i < 26; i++) {
      if (!occurred[i])
         cost += arr[i];
   }
   return cost;
}
int main(){
   int arr[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26 };
   string str = "abcdefghijklmopqrstuvwz";
   cout << calc_cost(arr, str);
   return 0;
}
