You are walking along a hiking trail. On this hiking trail, there is elevation marker at every kilometer. The elevation information is represented in an array of integers. For example, if the elevation array is [100, 50, 20, 30, 50, 40], that means at kilometer 0, the elevation is 100 meters; at kilometer 1, the elevation is 50 meters; at kilometer 2, the elevation is 20 meters; at kilometer 3, the elevation is 30 meters; at kilometer 4, the elevation is 50 meters; at kilometer 5, the elevation is 40 meters. a) Write a method called dangerousDescent that determines whether there is a downhill section in the hiking trail with a gradient of more than -5%. The gradient is calculated by the rise in elevation over the run in distance. For example, the last kilometer section has a gradient of -1% because the rise in elevation is 40 - 50
