3110. 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.

Constraints:

• 2 <= s.length <= 100
• s consists only of lowercase English letters.

Code

class Solution:
    def scoreOfString(self, s: str) -> int:
        total = 0

        for i in range(1, len(s)):
            total += abs(ord(s[i]) - ord(s[i - 1]))

        return total

function scoreOfString(s: string): number {
  let total = 0;

  for (let i = 1; i < s.length; i++) {
    total += Math.abs(s.charCodeAt(i) - s.charCodeAt(i - 1));
  }

  return total;
