INFORMATION PANEL #1 A hiking trail has elevation markers posted at regular intervals along the trail. Elevation information about a trail can be stored in an array, where each element in the array represents the elevation at a marker. The elevation at the first marker will be stored at array index 0, the elevation at the second marker will be stored at array index 1, and so forth. Elevations between markers are ignored in this question. The graph below shows an example of trail elevations. EVATION TRAIL ELEVATION 160 Elevation (meters) 140 120 100 80 60 40 20 0 1 2 3 4 5 6 7 8 9 10 11 12 Index The table below contains the data represented in the graph. Trail Elevation (meters) Index 0 1 2 3 4 5 6 7 Elevation 100 150 105 120 90 80 50 75 9 10 8 75 11 90 12 100 70 80 Your answer INFORMATION PANEL #2 The declaration of the Trail class is shown below. You will write two unrelated methods of the Trail class. * * public class Trail { /** Representation of the trail. The number of markers on the trail is markers.length. */ private int markers; /** Determines if a trail segment is level. A trail segment is defined by a starting marker, an ending marker, and all markers between those two markers. A trail segment is level if it has a difference between the maximum elevation and minimum elevation that is less than or equal to 10 meters. @param start the index of the starting marker @param end the index of the ending marker Precondition: 0
