What happens if the null path length is not updated?(a) error occurs(b

1.	What happens if the null path length is not updated?(a) error occurs(b) all null path lengths will be 0(c) all null path lengths will be -1(d) all null path lengths will be 1My query is from Heap topic in division Heap of Data Structures & Algorithms II had been asked this question in an online interview.
Answer» RIGHT choice is (b) all null path lengths will be 0 Explanation: While performing insertion VIA merge OPERATION in a leftist HEAP, if the null path length is not updated, all null path lengths will be 0.
