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 (Clang 3.8.0) (judge verdict: Wrong Answer)

#include <stdio.h>
int main()
{
   int N, T;
   int c, t;
   int i;
   int ans;
   scanf( "%d", &N );
   scanf( "%d", &T );
// printf("N=%d,T=%d\n", N, T);

   for( i=0, ans=0; i< N;  i++){
      scanf( "%d", &c );
      scanf( "%d", &t );
//  printf("i=%d,c=%d,t=%d,ans=%d\n", i, c, t, ans);

      switch( i ){
      case 0:
         if( t <= T ){
             ans = c;
         }
         break;
     default:
          if( t <= T && c < ans ){
             ans = c;
         }
     } /* switch */

// printf("i=%d,c=%d,t=%d,ans=%d\n", i, c, t, ans);
   } /* for i */

   if( ans == T ){
      printf( "TLE\n" );
   }else{
      printf( "%d\n", ans );
  }

  return 0;
