Problem:
Score : 200 points

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

5

Solution in C# (Mono 4.6.2.0) (judge verdict: Wrong Answer)

using System;

public class timeLimit
{
	public static void Main()
	{
		string[] hoge = Console.ReadLine().Split(' ');

		var n = int.Parse(hoge[0]);
		var t = int.Parse(hoge[1]);

		var min = 0; //minimum cost
		var f = false;

		for(int i = 0; i < n; i++)
		{
			string[] fuga = Console.ReadLine().Split(' ');


			if(int.Parse(fuga[1]) <= t)
			{
				f = false;

				if(i == 0)
				{
					min = int.Parse(fuga[0]);
				}
				else
				{
					if(int.Parse(fuga[0]) < min)
					{
						min = int.Parse(fuga[0]);
					}
				}
				
			}
			else
			{
				f = true;
			}
		}

		if(!f)
		{
			Console.WriteLine(min);
		}
		else
		{
			Console.WriteLine("TLE");
		}
		
	}
