Because a heap is a complete tree an unambiguous representation in tree form can be generated by outputting the heap level by level with each level output on a separate line. void writeLevels const Requirements None Results Outputs the data items in a heap in level order one level per line. Only outputs each data item s priority. If the heap is empty then outputs Empty heap . The tree shown on the first page of this laboratory for example yields the following output. 93 82 64 27 75 39 18 Step 1 Implement this operation and add it to the file . A prototype for this operation is included in the declaration of the Heap class in the file . Step 2 Activate the W write levels command in the test program in the file by removing the comment delimiter and the character W from the lines that begin with W . Step 3 Prepare a test plan for this operation that covers heaps of various sizes including empty and single-data item heaps. A test plan form follows. Step 4 Execute your test plan. If you discover mistakes in your implementation of the writeLevels operation correct them and execute your test plan again. 372 Laboratory B Test Plan for the writeLeveis Operation Test Case Commands Expected Result Checked
