    3117 - Minimum Sum of Values by Dividing Array.

    Hard

    You are given two arrays nums and andValues of length n and m respectively.

    The value of an array is equal to the last element of that array.

    You have to divide nums into m disjoint contiguous subarrays such that for the <code>i<sup>th</sup></code> subarray <code>l<sub>i</sub>, r<sub>i</sub></code>, the bitwise AND of the subarray elements is equal to andValues[i], in other words, <code>numsl<sub>i</sub>& numsl<sub>i</sub> + 1& ... & numsr<sub>i</sub> == andValuesi</code> for all 1 &lt;= i &lt;= m, where &amp; represents the bitwise AND operator.

    Return the minimum possible sum of the values of the m subarrays nums is divided into. If it is not possible to divide nums into m subarrays satisfying these conditions, return -1.

    Example 1:

    Input: nums = 1,4,3,3,2, andValues = 0,3,3,2

    Output: 12

    Explanation:

    The only possible way to divide nums is:

    • [1,4] as 1 &amp; 4 == 0.

    • [3] as the bitwise AND of a single element subarray is that element itself.

    • [3] as the bitwise AND of a single element subarray is that element itself.

    • [2] as the bitwise AND of a single element subarray is that element itself.

    The sum of the values for these subarrays is 4 + 3 + 3 + 2 = 12.

    Example 2:

    Input: nums = 2,3,5,7,7,7,5, andValues = 0,7,5

    Output: 17

    Explanation:

    There are three ways to divide nums:

    • [[2,3,5],[7,7,7],[5]] with the sum of the values 5 + 7 + 5 == 17.

    • [[2,3,5,7],[7,7],[5]] with the sum of the values 7 + 7 + 5 == 19.

    • [[2,3,5,7,7],[7],[5]] with the sum of the values 7 + 7 + 5 == 19.

    The minimum possible sum of the values is 17.

    Example 3:

    Input: nums = 1,2,3,4, andValues = 2

    Output: \-1

    Explanation:

    The bitwise AND of the entire array nums is 0. As there is no possible way to divide nums into a single subarray to have the bitwise AND of elements 2, return -1.

    Constraints:

    • <code>1 <= n == nums.length <= 10<sup>4</sup></code>

    • 1 &lt;= m == andValues.length &lt;= min(n, 10)

    • <code>1 <= numsi< 10<sup>5</sup></code>

    • <code>0 <= andValuesj< 10<sup>5</sup></code>
