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

#include <stdio.h>


int main(void){
    //nとttの読み取り
    int n, tt;
    scanf("%d %d", &n, &tt);
    //cとtの読み取り
    int i;
    int c[n], t[n];
    for(i = 0 ; i < n ; i++){
        scanf("%d %d", &c[i], &t[i]);
    }
    //計算
    int c_min;
    c_min = 1001;
    for(i = 0 ; i < n ; i++){
        if(t[i] <= tt){
            if(c[i] < c_min){
                c_min = c[i];
            }
        }
    }
    //表示
    if(c_min == 1001){
        printf("TLE\n");
    }
    else{
        printf("%d\n", c_min);
    }

    return 0;
}
