    3707 - Equal Score Substrings.

    Easy

    You are given a string s consisting of lowercase English letters.

    The score of a string is the sum of the positions of its characters in the alphabet, where 'a' = 1, 'b' = 2, ..., 'z' = 26.

    Determine whether there exists an index i such that the string can be split into two non-empty substrings s[0..i] and s[(i + 1)..(n - 1)] that have equal scores.

    Return true if such a split exists, otherwise return false.

    A substring is a contiguous non-empty sequence of characters within a string.

    Example 1:

    Input: s = "adcb"

    Output: true

    Explanation:

    Split at index i = 1:

    • Left substring = s[0..1] = "ad" with score = 1 + 4 = 5

    • Right substring = s[2..3] = "cb" with score = 3 + 2 = 5

    Both substrings have equal scores, so the output is true.

    Example 2:

    Input: s = "bace"

    Output: false

    Explanation:

    No split produces equal scores, so the output is false.

    Constraints:

    • 2 <= s.length <= 100

    • s consists of lowercase English letters.
