稀疏矩阵的元素值的范围为1~1000之间的整型数。利用随机函数按1 的非0元素概率生成这个矩阵，并将矩阵存入闭散列表中。并检验最后生成的非0元素的个数是否为1 -Sparse matrix elements of the scope of the value for 1 ~ 1000 between integer. The random functions with 1　of the 0 element probability generating the matrix, which closed list in matrix scattered. And inspection of the generation of the last element of the number is 0 to 1
