/**
 * [3165] Maximum Sum of Subsequence With Non-adjacent Elements
 *
 * You are given an array nums consisting of integers. You are also given a 2D array queries, where queries[i] = [posi, xi].
 * For query i, we first set nums[posi] equal to xi, then we calculate the answer to query i which is the maximum sum of a <span data-keyword="subsequence-array">subsequence</span> of nums where no two adjacent elements are selected.
 * Return the sum of the answers to all queries.
 * Since the final answer may be very large, return it modulo 10^9 + 7.
 * A subsequence is an array that can be derived from another array by deleting some or no elements without changing the order of the remaining elements.
 *  
 * <strong class="example">Example 1:
 * <div class="example-block">
 * Input: <span class="example-io">nums = [3,5,9], queries = [[1,-2],[0,-3]]</span>
 * Output: <span class="example-io">21</span>
 * Explanation:<br />
 * After the 1^st query, nums = [3,-2,9] and the maximum sum of a subsequence with non-adjacent elements is 3 + 9 = 12.<br />
 * After the 2^nd query, nums = [-3,-2,9] and the maximum sum of a subsequence with non-adjacent elements is 9.
 * </div>
 * <strong class="example">Example 2:
 * <div class="example-block">
 * Input: <span class="example-io">nums = [0,-1], queries = [[0,-5]]</span>
 * Output: <span class="example-io">0</span>
 * Explanation:<br />
 * After the 1^st query, nums = [-5,-1] and the maximum sum of a subsequence with non-adjacent elements is 0 (choosing an empty subsequence).
 * </div>
 *  
 * Constraints:
 * 
 * 	1 <= nums.length <= 5 * 10^4
 * 	-10^5 <= nums[i] <= 10^5
 * 	1 <= queries.length <= 5 * 10^4
 * 	queries[i] == [posi, xi]
 * 	0 <= posi <= nums.length - 1
 * 	-10^5 <= xi <= 10^5
 *
