Search a 2D Matrix

You are given an m x n integer matrix matrix with the following two properties:. Examples Example 1: Input: matrix = [[1,3,5,7],[10,11,16,20],[23,30,34,60]], target = 3 Output: true Example 2: Input: matrix = [[1,3,5,7],[10,11,16,20],[23,30,34,60]], target = 13 Output: false Constraints m == matrix.length n == matrix[i].length 1 <= m, n <= 100 -10^4 <= matrix[i][j], target <= 10^4
