You are given an integer n
and a 0-indexed 2D array queries
where queries[i] = [typei, indexi, vali]
.
Initially, there is a 0-indexed n x n
matrix filled with 0
's. For each query, you must apply one of the following changes:
typei == 0
, set the values in the row with indexi
to vali
, overwriting any previous values.typei == 1
, set the values in the column with indexi
to vali
, overwriting any previous values.Return the sum of integers in the matrix after all queries are applied.
Example 1:
Input: n = 3, queries = [[0,0,1],[1,2,2],[0,2,3],[1,0,4]] Output: 23 Explanation: The image above describes the matrix after each query. The sum of the matrix after all queries are applied is 23.
Example 2:
Input: n = 3, queries = [[0,0,4],[0,1,2],[1,0,1],[0,2,3],[1,2,1]] Output: 17 Explanation: The image above describes the matrix after each query. The sum of the matrix after all queries are applied is 17.
Constraints:
1 <= n <= 104
1 <= queries.length <= 5 * 104
queries[i].length == 3
0 <= typei <= 1
0 <= indexi < n
0 <= vali <= 105
