Step 1: Choose the middle point of the grid(6,6 in this case) and submit
Step 2: Now how much distance from the middle point and the treasure, plot all the possible answers in the grid
Step 3: Among the above, enter any one.
Step 4: Calculate distance between 1st point and 2nd point.
Step 5: If there is any intersection and only 1 common possible point, its the treasure
Step 6: Else, Now find grid points that is far away for 1st point and also far away from 2nd point and list all the possible points
Step 7: Choose one common possible point and enter as 3rd attempt
Step 8: If not correct, there would most probably be 1 point that is common between the 1st attempt, 2nd attempt and 3rd attempt. So, in the 4th attempt, you will find the treasure.
