Need help writing a method that prints out the words and the counts of all the words in the in the trie. I am providing the rest of my code in the file to you as to help with clarity and any methods that you may need to write the method.

method header----- void printTrieContents(node* trieNode);

IMPORTANT TO READ When printing out the counts of all the words in the trie, print out one line for each word with non-zero count, in alphabetical order. Do not print out words with 0 counts. To traverse the nodes in alphabetical order, you should print out the count for the root node of your trie (if non-zero), then recurse upon each child in alphabetical order. To keep track of the word associated with the current node, you can use a character buffer as a stack: every time you go down a level in the trie (i.e., make a recursive call), you add the corresponding character to the end of the buffer (i.e., push on the stack). When you go back up a level in the trie (i.e., return from a recursive call), you remove a character from the end of the buffer (i.e., pop off the stack). You should keep track of the buffer length and print an error message if the buffer is too small.
