Score Of A String
Compute the score of a string by summing the absolute differences of adjacent character codes.
Acceptance 0%
Problem Statement
Problem
Given a string s, define its score as the sum of the absolute differences between the ASCII values of every pair of adjacent characters.
For example, for s = "abc", the score is |a-b| + |b-c|.
Return the score of the string.
This is a straightforward character-by-character computation over the string.
Input Format
- A single string
s. - Characters are processed in order from left to right.
Output Format
- Return an integer representing the score of
s.
Constraints
- The string length is at least 1.
- The score is the sum of absolute differences of adjacent character codes.
- Character codes may be treated as ASCII/Unicode code points for the purpose of this problem, but standard lowercase-letter inputs are sufficient for practice.
Examples
Sample cases returned by the problem API.
Example 1
Input
s = "hello"
Output
13
Explanation
Adjacent differences are |'h'-'e'| = 3, |'e'-'l'| = 7, |'l'-'l'| = 0, and |'l'-'o'| = 3. The total is 13.
