Score of a String

You are given a string s. The score of a string is defined as the sum of the absolute difference between the ASCII values of adjacent characters. Return the score of s. 

Example 1:
Input: s = "hello"
Output: 13
Explanation:
The ASCII values of the characters in s are: 'h' = 104, 'e' = 101, 'l' = 108, 'o' = 111. So, the score of s would be |104 - 101| + |101 - 108| + |108 - 108| + |108 - 111| = 3 + 7 + 0 + 3 = 13.

Example 2:
Input: s = "zaz"
Output: 50
Explanation:
The ASCII values of the characters in s are: 'z' = 122, 'a' = 97. So, the score of s would be |122 - 97| + |97 - 122| = 25 + 25 = 50.


class Solution {
    public int scoreOfString(String s) {
        int score=0;
        for(int i=1;i<s.length();i++)
        {
            char curr=s.charAt(i);
            char prev=s.charAt(i-1);
            score+=Math.abs((int)curr-(int)prev);
        }
        return score;
    }
}
