LeetCode 240. Search a 2D Matrix II

Solution1:
为什么把第74题的代码改都不用改的拿过来就可以AC，一脸懵逼啊。。。

class Solution {
public:bool searchMatrix(vector<vector<int>>& matrix, int target) {if (!matrix.size() || !matrix[0].size()) return false;int m = matrix.size() - 1, n = matrix[0].size() - 1, i = 0, j = n;while (i <= m && j >= 0) {if (matrix[i][j] == target) return true;else if (matrix[i][j] < target) i++;else j--;}return false;}
};
