HackerEarth String Sum problem solution

In this HackerEarth String Sum problem solution Consider All lowercase Alphabets of the English language. Here we consider each alphabet from a to z to have a certain weight. The weight of the alphabet a is considered to be 1, b to be 2, c to be 3, and so on until z has a weight of 26. In short, the weight of the alphabet a is 1, and the weight of all other alphabets is the weight of its previous alphabet + 1.

Now, you have been given a String S consisting of lowercase English characters. You need to find the summation of the weight of each character in this String.
