Sorted Linked List duplicates removal - Facebook code lab

July 16, 2016

  Julia spent over 1 hour to work on this question. So, her first two practices using facebook code lab:

1. Use recursive function - stack overflow issue

2. Use iteration solution, but run time performance needs to improve (July15, 2016)/ unreachable code, showing different error messages on July 16, 2016

Then, Julia spent 20 minutes to think if she should use binary search to expedite the search not distinct node - extra array to help, but then, she checked the code lab.

Recall her previous blog on the linked list:

(Pass HackerRank test, but fail facebook code lab test? double check)

Her favorite solution: (Pass facebook code lab test)
