Thanks to our parents, they gave us life and raised us adults;
Thanks to the teachers, they taught us knowledge and taught us how to behave.
Thanks to our friends, they make us feel the warmth of the world;
Thanks to our competitors, they have made us enterprising and hard.
We also want to thank the wealth that the pain and hardships have brought us ~
Input data first contains a positive integer c, indicating that there are C test cases. The first line of each test case is two integers n and M (1 <= n <= 100, 1 <= m <= 100), indicating the amount of funds and the type of rice, followed by m rows of data, each row contains 3 numbers P, H and C (1 <= P <= 20, 1 <= H <=, 1 <= C <= 20 ), the price of each bag, the weight of each bag, and the number of bags of the corresponding rice.
Output for each group of test data, please output the maximum weight of the rice that can be purchased. You can assume that the cost is not only for all the rice, but you don't have to finish the cost. The output of each instance occupies one row.
