# Merge two sorted linked lists and return it as a sorted list. The list should be made by splicing together the nodes of the first two lists.


# Example 1:


# Input: l1 = [1,2,4], l2 = [1,3,4]
# Output: [1,1,2,3,4,4]
# Example 2:

# Input: l1 = [], l2 = []
# Output: []
# Example 3:

# Input: l1 = [], l2 = [0]
# Output: [0]
