    1312 - Minimum Insertion Steps to Make a String Palindrome.

    Hard

    Given a string s. In one step you can insert any character at any index of the string.

    Return the minimum number of steps to make s palindrome.

    A Palindrome String is one that reads the same backward as well as forward.

    Example 1:

    Input: s = “zzazz”

    Output: 0

    Explanation: The string “zzazz” is already palindrome we don’t need any insertions.

    Example 2:

    Input: s = “mbadm”

    Output: 2

    Explanation: String can be “mbdadbm” or “mdbabdm”.

    Example 3:

    Input: s = “leetcode”

    Output: 5

    Explanation: Inserting 5 characters the string becomes “leetcodocteel”.

    Constraints:

    • 1 <= s.length <= 500
    • s consists of lowercase English letters.
