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

4 10
1000 1000
6 1

Sample Output 3

fun main(args: Array<String>) {
    val line = readLine()!!.split(' ').map { it.toInt() }
    val n = line[0]
    val t = line[1]
    var ans = -1
    var isFirst = true
    for (i in (1..n)) {
        val l = readLine()!!.split(' ').map { it.toInt() }
        if (isFirst && l[1] <= t || l[0] < ans && l[1] <= t) {
            ans = l[0]
            isFirst = false
        }
    }
    if (ans == -1) {
        println("TLE")
    } else {
        println(ans)
    }
