二维数组中的查找

题目描述

在一个二维数组中(每个一维数组的长度相同),每一行都按照从左到右递增的顺序排序,每一列都按照从上到下递增的顺序排序。请完成一个函数,输入这样的一个二维数组和一个整数,判断数组中是否含有该整数。

class Solution {
public:
    bool Find(int target, vector<vector<int> > array) {
        int rowCount = array.size();
        int colCount = array[0].size();
        int i,j;
        for(i=rowCount-1,j=0;i>=0&&j<colCount;){
            if(target == array[i][j])
                return true;
            if(target < array[i][j]){
                i--;
                continue;
            }
            if(target > array[i][j]){
                j++;
                continue;
            }
        }
        return false;
    }
};
