Problem Statement

When Mr. X is away from home, he has decided to use his smartwatch to search the best route to go back home, to participate in ABC.

You, the smartwatch, has found N routes to his home.

If Mr. X uses the i-th of these routes, he will get home in time t_i at cost c_i.

Find the smallest cost of a route that takes not longer than time T.

Constraints

• All values in input are integers.
• 1 \leq N \leq 100
• 1 \leq T \leq 1000
• 1 \leq c_i \leq 1000
• 1 \leq t_i \leq 1000
• The pairs (c_i, t_i) are distinct.

Input

Input is given from Standard Input in the following format:

N T
c_1 t_1
c_2 t_2
:
c_N t_N


Output

Print the smallest cost of a route that takes not longer than time T.

If there is no route that takes not longer than time T, print TLE instead.

Sample Input 1

3 70
7 60
1 80
4 50


Sample Output 1

4

• The first route gets him home at cost 7.
• The second route takes longer than time T = 70.
• The third route gets him home at cost 4.

Thus, the cost 4 of the third route is the minimum.
