求字符串中字符字母顺序的总和

原文:https://www . geesforgeks . org/find-按字母顺序排列的字符串字符总和/

给定大小为 N 的字符串 S ，任务是找出给定字符串中每个字符的字母值之和。

示例:

输入: S =“极客”

输出: 28

说明:
字母的和序得到的值是 7 + 5 + 5 + 11 = 28。

输入: S = "GeeksforGeeks "

输出: 133

进场:

• 遍历给定字符串中的所有字符


• 对于每个小写字符，将值(S[I]–‘A’+1)添加到最终答案，或者如果是大写字符，将(S[I]–‘A’+1)添加到最终答案。

下面是上述方法的实现:

C++

// C++ program for the above approach
#include
using namespace std;
int findTheSum(string alpha)
{
    // Stores the sum of order of values
    int score = 0;
    for (int i = 0; i     {
        // Find the score
        if (alpha[i] >= 'A' && alpha[i] <= 'Z')
            score += alpha[i] - 'A' + 1;
        else
            score += alpha[i] - 'a' + 1;
    }
    // Return the resultant sum
    return score;
}
// Driver Code
int main()
{
    string S = "GeeksforGeeks";
    cout <    return 0;
}


Java 语言(一种计算机语言，尤用于创建网站)

// Java code to implement the above approach
import java.util.*;
public class GFG
{
static int findTheSum(String alpha)
{
    // Stores the sum of order of values
    int score = 0;
    for (int i = 0; i     {
        // Find the score
        if (alpha.charAt(i) >= 'A' && alpha.charAt(i) <= 'Z')
            score += alpha.charAt(i) - 'A' + 1;
        else
            score += alpha.charAt(i) - 'a' + 1;
    }
    // Return the resultant sum
    return score;
}
// Driver code
public static void main(String args[])
{
    String S = "GeeksforGeeks";
    System.out.println(findTheSum(S));
}
}

Python 3

# Python3 program for the above approach
def findTheSum(alpha):
    # Stores the sum of order of values
    score = 0
    for i in range(0, len(alpha)):
        # Find the score
        if (ord(alpha[i]) >= ord('A') and ord(alpha[i]) <= ord('Z')):
            score += ord(alpha[i]) - ord('A') + 1
        else:
            score += ord(alpha[i]) - ord('a') + 1
    # Return the resultant sum
    return score
# Driver Code
if __name__ == "__main__":
    S = "GeeksforGeeks"
    print(findTheSum(S))
