【数据结构】 稀疏矩阵 转换成三元组_python将一个稀疏矩阵存为三元表

# include <stdio.h>
# define maxsize 100
 
//三元组结点：
typedef int datatype;
typedef struct
{ 
	int x;
	int y;
	datatype value;
} Triple;
 
//稀疏矩阵：
typedef struct 
{ 
	Triple data[maxsize];
	int row;
	int val;
	int num;/*行、列、非零元素个数*/  
} TsMatrix;
 
void main()
{
	int m = 1;
	TsMatrix matrix = {0,};
 
	int array[8][8] = 
	{
		0,2,0,2,1,0,3,1,
		0,1,0,0,0,0,0,2,
		0,1,5,0,0,1,5,0,
		0,0,0,0,5,0,5,0,
		0,3,0,0,5,0,0,0,
		8,0,0,0,0,0,0,0,
		0,0,0,0,5,0,5,0,
		0,0,0,0,5,0,0,6,
	};
 
	matrix.row = 8;
	matrix.val = 8;
 
	for (int i = 0; i < 8; i ++)
	{
		for (int j = 0; j < 8; j++)
		{
			if (array[i][j])
			{
				matrix.num ++;
				matrix.data[m].x = i;
				matrix.data[m].y = j;
				matrix.data[m].value = array[i][j];
 
				m++;
			}
		}
	}
 
	for (int i = 0; i < m; i++)
	{
		printf("%d %d %d\n",matrix.data[i].x,matrix.data[i].y,matrix.data[i].value);
