制作一串 Panagram 的成本
给定一个数组arr【】包含添加来自(a–z)的每个字母表的成本，以及一个字符串 str ，它可能是也可能不是一个 Panagram 。任务是找到制作字符串 Panagram 的总成本。
示例:
输入: 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}， str = " abcdefghijklmopsutvwz " T4】输出: 63 n，x 和 y 是唯一缺少的字符 它们的成本分别是 14、24、25。 因此，总成本= 14 + 24 + 25 = 63
输入: 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}， str = " The quickbrownfoxpjumpershiphelazydog " 输出: 0 该字符串已经是一个 Pangram，因为它包含了所有
方法:标记所有出现在字符串中的(a–z)的字母，然后找到字符串中缺失的字母。将这些缺失字母的成本相加，得到制作字符串 Pangram 所需的总成本。
下面是上述方法的实现:
C++
// C++ program to find the cost to make a string Panagram
#include <bits/stdc++.h>
using namespace std;
// Function to return the total cost required
// to make the string Pangram
int pangramCost(int arr[], string str)
{
int cost = 0;
bool occurred[26] = { false };
// Mark all the alphabets that occurred in the string
for (int i = 0; i < str.size(); i++)
occurred[str[i] - 'a'] = true;
// Calculate the total cost for the missing alphabets
for (int i = 0; i < 26; i++) {
if (!occurred[i])
cost += arr[i];
}
return cost;
}
// Driver Code
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 << pangramCost(arr, str);
return 0;
}
