Charlie just downloaded the new free to play game Raid Shadow Legends Conquest. Just what he wanted! In this game, he must defeat enemies, all of which are bots, and restore power to his clan. Both Charlie and the enemy before him start with H health points. Then, the two take turns performing actions, with Charlie going first. On each turn, one can perform one of two actions:

  • A d Attack your opponent, dealing d damage.
  • D d Dodge your opponent if they attack on the next turn. If they do not attack on the next turn, take d damage from self-humility.

Because he is such a computer genius, Charlie has hacked the game and created two lists of N actions each representing what the opponent will do and what he will do. Your job is to simulate his battle and find out who wins. If any person's health reaches 0 or below, your program is to output the correct answer and terminate.

Note: Dodging at the end of the list of actions counts as a failed dodge. (i.e. if the enemy prepares a dodge as their last move, they will inflict self harm.)

Input Specification

The first line of input contains two space separated positive integers N and H.

The next N lines contain an uppercase Latin letter and a non-negative integer d representing Charlie's actions.

The next N lines contain an uppercase Latin letter and a non-negative integer d representing his opponent's actions.

Output Specification

Output VICTORY if Charlie wins or DEFEAT if he loses or TIE if none of them die.

Constraints

1 \le N, H \le 1000

0 \le d \le 1000

Sample Input 1

3 100
A 50
D 10
A 100
A 90
D 0
A 0

Sample Output 1

DEFEAT

Sample Explanation

After the first turn, the bot's health is at 50. After the second turn, Charlie's health is at 10. After the third turn, Charlie attempts to dodge the next attack but his opponent also dodges causing Charlie's health to drop to 0. The remaining commands are ignored due to Charlie losing.

Sample Input 2

4 100
D 10
D 20
D 30
D 30
D 10
D 20
D 30
D 40

Sample Output 2

VICTORY

Sample Explanation 2

After the second last turn, Charlie's health is at 10 and his opponent's is at 40. Then, his opponent tries to dodge but Charlie does not attack (because the list of actions have been completed) and his opponent takes 40 damage reducing their health to 0.

Sample Input 3

2 100
A 99
