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.

Sample Input 2

4 3
1 1000
2 4
3 1000
4 500

Sample Output 2

TLE

There is no route that takes not longer than time T = 3.

Sample Input 3

5 9
25 8
5 9
4 10
1000 1000
6 1

Sample Output 3

Solution in Ruby (2.3.3) (judge verdict: Accepted)

# Time Limit Exceeded
N,T = gets.chomp.split(" ").map(&:to_i)
c = []
t = []
time_min = 1001
cost_min = 1001
ans_index = 0
flg = 0
for i in 0..N-1 do
    c[i],t[i] = gets.chomp.split(" ").map(&:to_i)
    if t[i] <= T && c[i] < cost_min
        ans_index = i
        time_min = t[i]
        cost_min = c[i]
        flg = 1
    end
end
if flg == 1 
    puts c[ans_index]
elsif flg == 0
    puts "TLE"    
end
