We can use run-length encoding (i.e., RLE) to encode a sequence of integers. In a run-length encoded array of even length encoding (0-indexed), for all even i, encoding[i] tells us the number of times that the non-negative integer value encoding[i + 1] is repeated in the sequence. For example, the sequence arr = [8,8,8,5,5] can be encoded to be encoding = [3,8,2,5]. encoding = [3,8,0,9,2,5] and encoding = [2,8,1,8,2,5] are also valid RLE of arr. Given a run-length encoded array, design an iterator that iterates through it. Implement the RLEIterator class: RLEIterator(int[] encoded) Initializes the object with the encoded array encoded. int next(int n) Exhausts the next n elements and returns the last element exhausted in this way.
