Input Specification:

Each input file contains the one test case. For each test case, the first line contains 4 positive integers:N≤)-The number of cities (and the cities is numbered from 0 toN?1),M-the number of roads,C?1?? andC?2?? -The cities that is currently in and so you must save, respectively. The next line containsN integers, where thei-th Integer is the number of rescue teams in theI-th City. ThenM lines follow, each describes a road with three integersC?1??,C?2?? andL, which is the pair of cities connected by a road and the length of this road, respectively. It is guaranteed this there exists at least one path fromc< Span class= "Vlist" >?1??  to < Span class= "base textstyle uncramped" >c? 2? ?.

Output Specification:

For all test case, print in one line numbers:the number of different shortest paths betweenC? 1 ??  and < Span class= "base textstyle uncramped" >c? 2? ?, and the maximum amount of rescue teams you can possibly gather. All the numbers in a line must being separated by exactly one space, and there are no extra space allowed at the end of a line .

Sample Input:
5 6 0 2

0 2 2
0 3 1
1 2 1

Sample Output:
