InterviewBit Problems   Min XOR value : Unsolved

About the Min XOR value : Unsolved category (1)
Easy to understandable and efficient algorithm (3)
Why we need to sort first? Thanks in advance (2)
Why can't we use Trie? (2)
More efficient solution as compare to given Solution (1)
Code submitted, but issues with testing (2)
Optimal Solution:O(n) (3)
You should not Try Trie! (1)
Need help to understand question better (5)
Tiime limit exceeded:Got partial marks (2)
Solution got accepted, but I am not able to find why it may be wrong (1)
Why seg fault whilw workinf for test case? (1)
Can somebody please explain logic behind nlogn(sorting) code (3)
Issue with submission (4)
Trading Space Complexity with Time (1)
Time limit exceed even after sorting the array (2)
Using Trie, It is giving memory exceeded. but Problem is solved in O(n) (2)
Memory Limit Exceeded: getting partially correct answer using recursion (1)
Contrasting behavior of test case and custom case (3)
Time limit has exceeded (2)
Is the array sorted, or not? (2)
