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: Wrong Answer)

$info1=gets.chomp.split(" ").map(&:to_i)
info2=Array.new($info1[0])
$info1[0].times do|i|
	info2[i]=gets.chomp.split(" ").map(&:to_i)
end
def mysort(_listdata)
	for i in (0..$info1[0]-1)
		indexmin=i
		for j in (i..$info1[0]-1)
			if(_listdata[j][0]<_listdata[indexmin][0])
				indexmin=j
			end
		end
			w=_listdata[i]
			_listdata[i]=_listdata[indexmin]
			_listdata[indexmin]=w
	end
	return _listdata
end
info=mysort(info2)
for i in (0..$info1[0]-1) do
	if($info1[1]>=info[i][1])
		p info[i][0]
		break
	end
	if i==$info1[0]-1
		p "TLE"
	end
