Domino Chain

Mubashir was playing with dominos. He concluded that:

• If the first domino is pushed over, it will keep tipping next dominos to its right.
• Reaction will stop if a domino is already tipped over, or if there is an empty space.

Create a function which takes a string of current status of the dominos and returns the string after dominos chain reaction.

• "|" represents a standing domino.
• "/" represents a tripped domino.
• " " represents an empty space.

Examples

domino_chain("||| ||||//| |/") ➞ "/// ||||//| |/"
// A space will stop the reaction.

domino_chain("||//||") ➞ "////||"
// An already tripped domino will stop the reaction.

domino_chain("||||") ➞ "////"
