二维数组的查找，刷题成功——剑指Offer

class Solution {
public:
    bool Find(int target, vector<vector<int> > array) {
        int rlen = array.size();
        if (rlen == 0) return false;
        int clen = array[0].size();
        if (clen == 0) return false;
        
        int row = 0;
        int col = clen - 1;
        
        bool found = false;
        while (true) {
            if (row >= rlen || col < 0) break;
            
            if (array[row][col] == target) {
                found = true;
                break;
            }
            if (array[row][col] < target) {
                row++;
            }
            else {
                col--;
            }
        }
