Problem 2: Number of runs 50 pts Given an integer array, implement a static method num0fRuns (int[] arr) in Runs.java, to compute the number of runs in the integer array arr. A run is defined as a non-decreasing sequence of numbers. For example, 1, 2, 3 is a run. An array {2, 3, 3, 2} has two runs: 2, 3, 3, and ● • 2.
