13 caves are arranged in a circle at the temple of doom. One of these caves has the treasure of gems and wealth. Each day the treasure keepers can move the treasure to an adjacent cave or can keep it in the same cave. Every day two treasure seekers visit the place and have enough time to enter any two caves of their choice.

How do the treasure seekers ensure that they find the treasure in minimum possible days ?

If one of the treasure seeker moves clockwise every day and one of the treasure seeker moves anti clockwise, they will find the treasure in minimum seven days.
