//二维数组的创建、查询、销毁

int **create(int m,int n)

    int **arr=new int*[m];
    for(int i=0;i<m;i++)
    
        arr[i]=new int[n]; 
    
    
    return arr;


int search(int **arr,int m,int n,int x,int y)

    assert(x<=m-1&&y<=n-1);
        
    return *(*(arr+x)+y);


void destr(int **arr,int m,int n)

    for(int i=0;i<m;i++)
    
        delete []arr[i];
    
    delete []arr;
