Edge-test-3 failing

Edge-case-3 is failing for my code. I have tried all the edge cases I can think and have also tested all the methods of my code individually. Moreover my code is similar to the code shown in the sample video except for the merge method where I am using recursion.
Can I get one Edge case so that I can check what am I missing

Edge case 3 is a large test case consisting of a linked list of size 10000 , so providing you with a test case wont help your cause . Since the test cases that are failing are large in size it could be that your merge function is having a stack overflow during recursion(as the merge is done recursively too). You could try an iterative merge function and submit.
