Need help with trying to rewrite the getFrequencyOf method using recursion. I will provide the original non recursive code also. Try not to use the toArray method and use node chain.    Non-recursive method public int getFrequencyOf(T anEntry) { int frequency = 0; int counter = 0; Node currentNode = firstNode; while ((counter < numberOfEntries) && (currentNode != null)) { if (anEntry.equals(currentNode.data)) { frequency++; } counter++; currentNode = currentNode.next; }  return frequency; }

Merge sort

Merge Sort recursively sorts a given collection of numbers or elements by using the divide and conquer strategy in less time. It is one of the most used algorithms, with the worst-case time complexity of O (n log n). It was invented by John Von Neumann. The algorithm continuously divides an array into sub-arrays until each sub-array consists of a single element. It then merges those sub-arrays to produce a sorted array.
