LeetCode in Kotlin
3110. Score of a String
Easy
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 <= 100sconsists only of lowercase English letters.
Solution
import kotlin.math.abs
class Solution {
fun scoreOfString(s: String): Int {
var sum = 0
for (i in 0 until s.length - 1) {
sum += abs(((s[i].code - '0'.code) - (s[i + 1].code - '0'.code)))
}
return sum
}
}
