Domino Chain

Published by Mubashir Hassan in

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.

Mubashir

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

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

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

dominoChain("||||") ➞ "////"
