You are standing in a few inches of sea water on a beach.
You are wondering whether the high tide is coming soon or it has just passed.
Therefore, you will write a code in MATLAB to analyze following data.
You followed the sequence of water lines left by several swash of waves.
The data array A contains the distances the water traveled past your feet during each upward swash of waves.
Your code will return 1 if the high tide is coming soon.
Your code will return 0 if the high tide has just passed.
