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: 13Explanation: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: 50Explanation: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 <= 100s consists only of lowercase English letters.

Solution

To solve this problem, you can follow these steps:

  1. Initialize a variable score to 0. This will hold the total score of the string.

  2. Convert the string s into a list of characters.

  3. Iterate over the list of characters. For each character, get its ASCII value using the ord() function in Python.

  4. Calculate the absolute difference between the ASCII value of the current character and the ASCII value of the next character. Add this difference to score.

  5. Continue this process until you have iterated over all the characters in the string.

  6. Return score as the final score of the string.

Here is a Python code snippet that implements these steps:

def string_score(s):
    score = 0
    for i in range(len(s) - 1):
        score += abs(ord(s[i]) - ord(s[i+1]))
    return score

You can call this function with a string to get its score. For example:

print(string_score("hello"))  # Output: 13
print(string_score("zaz"))  # Output: 50

This function works for strings of length 2 to 100 and consisting only of lowercase English letters, as per the problem constraints.
