2020年8月19日华为笔试

今天做了华为机考题，第一题
给定一个二维数组，M行N列
顺时针从1开始报数，选出个位数为7，十位数为奇数的数，并按报数顺序输出出来
题目大概就是这样，这个题目和剑指offer的29题：顺时针打印矩阵非常相似
以下代码把给的例子输入进去结果是正确的，但是给定的输出格式不对，导致0%，好气

#include <iostream>
using namespace std;
void selectpeople(int M,int N);
void GoCircle(int **numbers,int m,int n,int start);
bool check(int result);
int data = 1;

{
	int m,n;
	cin >> m >> n;
	selectpeople(m,n);
	system("pause");
	return 0;
