You are given an integer n representing an array colors of length n where all elements are set to 0's meaning uncolored. You are also given a 2D integer array queries where queries[i] = [indexi, colori]. For the ith query:
colors[indexi] to colori.colors which have the same color (regardless of colori).Return an array answer of the same length as queries where answer[i] is the answer to the ith query.
\n
Example 1:
\n\nInput: n = 4, queries = [[0,2],[1,2],[3,1],[1,1],[2,1]]
\n\nOutput: [0,1,1,0,2]
\n\nExplanation:
\n\nExample 2:
\n\nInput: n = 1, queries = [[0,100000]]
\n\nOutput: [0]
\n\nExplanation:
\n\nAfter the 1st query colors = [100000]. The count of adjacent pairs with the same color is 0.
\n\n
Constraints:
\n\n1 <= n <= 1051 <= queries.length <= 105queries[i].length == 20 <= indexi <= n - 11 <= colori <= 105给定一个整数 n 表示一个长度为 n 的数组 colors，初始所有元素均为 0 ，表示是 未染色 的。同时给定一个二维整数数组 queries，其中 queries[i] = [indexi, colori]。对于第 i 个 查询：
colors[indexi] 染色为 colori。colors 中颜色相同的相邻对的数量（无论 colori）。请你返回一个长度与 queries 相等的数组 answer ，其中 answer[i]是前 i 个操作的答案。
\n\n
示例 1：
\n\n输入：n = 4, queries = [[0,2],[1,2],[3,1],[1,1],[2,1]]
\n\n输出：[0,1,1,0,2]
\n\n解释：
\n\n示例 2：
\n\n输入：n = 1, queries = [[0,100000]]
\n\n输出：[0]
\n\n解释：
\n\n在第一次查询后 colors = [100000]。颜色相同的相邻对的数量是 0。
