3498. Reverse Degree of a String Easy

1/**
2 * [3498] Reverse Degree of a String
3 *
4 * Given a string s, calculate its reverse degree.
5 * The reverse degree is calculated as follows:
6 * <ol>
7 * 	For each character, multiply its position in the reversed alphabet ('a' = 26, 'b' = 25, ..., 'z' = 1) with its position in the string (1-indexed).
8 * 	Sum these products for all characters in the string.
9 * </ol>
10 * Return the reverse degree of s.
11 *  
12 * <strong class="example">Example 1:
13 * <div class="example-block">
14 * Input: <span class="example-io">s = "abc"</span>
15 * Output: <span class="example-io">148</span>
