Problem Description

background:
Philip likes to play the QQ game of Snooker when he wants a relax, though he was just a little vegetable-bird. Maybe you hadn't played that game yet, no matter, I'll introduce the rule for you first.
There are 21 object balls on board, including 15 red balls and 6 color balls: yellow, green, brown, blue, pink, black.
The player should use a white main ball to make the object balls roll into the hole, the sum of the ball's fixed value he made in the hole is the player's score. The player should firstly made a red ball into the hole, after that he gains red-ball's value(1 points), then he gets the chance to make a color ball, then alternately. The color ball should be took out until all the red-ball are in the hole. In other word, if there are only color balls left on board, the player should hit the object balls in this order: yellow(2 point), green(3 point), brown(4 point), blue(5 point), pink(6 point), black(7 point), after the ball being hit into the hole, they are not get out of the hole, after no ball left on board, the game ends, the player who has
the higher score wins the game. PS: red object balls never get out of the hole.
I just illustrate the rules that maybe used, if you want to contact more details, visit http://sports.tom.com/snooker/ after
the contest.

for example, if there are 12 red balls on board(if there are still red ball left on board, it can be sure that all the color
balls must be on board either). So suppose Philp can continuesly hit the ball into the hole, he can get the maximun score is
12 * 1 (12 red-ball in one shoot) + 7 * 12(after hit a red ball, a black ball which was the most valuable ball should be the target) + 2 + 3 + 4 + 5 + 6 + 7(when no red ball left, make all the color ball in hole).
Now, your task is to judge whether Philip should make the decision to give up when telling you the condition on board(How many object balls still left not in the hole and the other player's score). If Philp still gets the chance to win, just print "Yes", otherwise print "No". (PS: if the max score he could get on board add his current score is equal to the opponent's current score, still output "Yes")

 

Input

The first line contains a numble N indicating the total conditions. Then followed by N lines, each line is made of three integers:
Ball_Left P_Score O_Score represeting the ball number left on board, Philp's current score, and the opponent's current score.
All the input value are in 32 bit integer value range.

 

Output

You should caculate the max score left Philp can gain, and judge whether he has the possiblity to win.

 

Sample Input

212 1 11 30 39

 

Sample Output

YesNo
//题意：输入n,a,b；n表示剩余几个球，a表示你的分数，b表示对手的分数，
斯诺克，有15个球9个红球，6个有色球，红球一个1分，有色球yellow(2 point), green(3 point), brown(4 point), blue(5 point), pink(6 point), black(7 point)，现在打球得分的规则是：每打进一个红球，接着得打进一个有色球（比如你打进一个红球，接着有打进一个黑球，那么你得分为8分），在红球没打完之前，打进的有色球得再将其拿出来，如果红球打完了，打进的有色球不必拿出来，现在告诉你的分数和对手的分数，如果你将剩下的球都打进，问你是否可以获得胜利，只要最终的a>=b，即为获胜。
一个水题，就是题太长，不好翻译。。。
