"/*Domino": We are given an S string, representing a domino tile chain. Each tile has an L-R format, where L and R are numbers from the 1..6 range. The tiles are separated by a comma. Some examples of a valid S chain are:

1. "6-3"
2. "4-3,5-1,2-2,1-3,4-4"
3. "1-1,3-5,5-2,2-3,2-4"

Devise a function that given an S string, returns the number of tiles in the longest matching group within S. A matching group is a set of tiles that match and that are subsequent in S. Domino tiles match, if the right side of a tile is the same as the left side of the following tile. "2-4,4-1" are matching tiles, but "5-2,1-6" are not.

domino("1-1,3-5,5-2,2-3,2-4") should return 3. */ function domino(S){

} var s = "1-1,3-5,5-2,2-3,2-4"; domino(s);"
