Question about the task Remove duplicate strings
Java Syntax, Level 5, Lesson 3
Under discussion
Fails validation but outputs correctly I worked for a long time on this and was able to figure it out this morning, but it failed both criteria for validation? I am able to set duplicates to null, beyond what the input is, e.g., "hello" "hello" "hello". I am really stumped as to why the first validation requirement is not being met?
