input is giving correct result but test cases are not passing
Output correct but test cases not passing
est cases still not passing

n1 and n2 can be 0 as well so handle that case
still not working. i have again saved the code.
check this.
u were again declaring node in ur else statement.
it’s not passing, and this linked list with 0 element is one case whereas while i’m submitting this code none of the test cases are passing

remove this return 0; statement from ur code.
yeah, now it passed, but why? This was’nt happening in any other code.
@akshatkaush
return 0; tells that program execution is finished successfully.
in ur code u are returning 0 just after ur first testcase which is wrong because some other testcases are there as well ,u should first complete execution for all test cases and then only return 0.
