Algorithms

You are given a string <code>s</code>. 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 <code>s</code>.

&nbsp;
Example 1:

<div class="example-block">
Input: s = &quot;hello&quot;

Output: 13

Explanation:

The ASCII values of the characters in <code>s</code> are: <code>&#39;h&#39; = 104</code>, <code>&#39;e&#39; = 101</code>, <code>&#39;l&#39; = 108</code>, <code>&#39;o&#39; = 111</code>. So, the score of <code>s</code> would be <code>|104 - 101| + |101 - 108| + |108 - 108| + |108 - 111| = 3 + 7 + 0 + 3 = 13</code>.
</div>

Example 2:

<div class="example-block">
Input: s = &quot;zaz&quot;

Output: 50

Explanation:

The ASCII values of the characters in <code>s</code> are: <code>&#39;z&#39; = 122</code>, <code>&#39;a&#39; = 97</code>. So, the score of <code>s</code> would be <code>|122 - 97| + |97 - 122| = 25 + 25 = 50</code>.
</div>

&nbsp;
Constraints:

<ul>
	<li><code>2 &lt;= s.length &lt;= 100</code></li>
	<li><code>s</code> consists only of lowercase English letters.</li>
</ul>

scoreOfString

Score of a String

String

给你一个字符串&nbsp;<code>s</code>&nbsp;。一个字符串的&nbsp;分数&nbsp;定义为相邻字符 ASCII&nbsp;码差值绝对值的和。

请你返回 <code>s</code>&nbsp;的 分数&nbsp;。

&nbsp;

示例 1：

<div class="example-block">
输入：s = "hello"

输出：13

解释：

<code>s</code>&nbsp;中字符的 ASCII 码分别为：<code>'h' = 104</code>&nbsp;，<code>'e' = 101</code>&nbsp;，<code>'l' = 108</code>&nbsp;，<code>'o' = 111</code>&nbsp;。所以&nbsp;<code>s</code>&nbsp;的分数为&nbsp;<code>|104 - 101| + |101 - 108| + |108 - 108| + |108 - 111| = 3 + 7 + 0 + 3 = 13</code>&nbsp;。
</div>

示例 2：

<div class="example-block">
输入：s = "zaz"

输出：50

解释：

<code>s</code>&nbsp;中字符的 ASCII&nbsp;码分别为：<code>'z' = 122</code>&nbsp;，<code>'a' = 97</code>&nbsp;。所以&nbsp;<code>s</code>&nbsp;的分数为&nbsp;<code>|122 - 97| + |97 - 122| = 25 + 25 = 50</code>&nbsp;。
</div>

&nbsp;

提示：

<ul>
	<li><code>2 &lt;= s.length &lt;= 100</code></li>
	<li><code>s</code>&nbsp;只包含小写英文字母。</li>
</ul>
