句子中每个单词的 ASCII 值的总和

给定一个英文句子（也可以包含数字），我们需要计算并打印该句子中每个单词的字符的 ASCII 值的总和。
例子：

Input :  GeeksforGeeks, a computer science portal for geeks
Output : Sentence representation as sum of ASCII each character in a word:
         1361 97 879 730 658 327 527 
         Total sum -> 4579
Here, [GeeksforGeeks, ] -> 1361, [a] -> 97, [computer] -> 879, [science] -> 730
      [portal] -> 658, [for] -> 327, [geeks] -> 527 

Input : I am a geek
Output : Sum of ASCII values:
         73 206 97 412 
         Total sum -> 788

方法：

1. 遍历字符串的长度并继续将字符转换为它们的 ASCII
2. 继续累加值直到句子结束。
3. 当我们遇到空格字符时，我们存储为该单词计算的总和并将总和再次设置为零。
4. 稍后，我们打印元素

输出：

Sum of ASCII values:
1317 97 879 730 658 327 495 
Total sum -> 4503

该方法的复杂性是$O(len)$
