Merge Two Sorted Lists

← Merge Two Sorted Lists medium

algorithms

Write a function solution(a, b) that merges two sorted lists into one sorted list.

Example

solution([1, 3, 5], [2, 4, 6]) → [1, 2, 3, 4, 5, 6]
solution([1], [])              → [1]

Every challenge runs your code by calling a function. You must define a function named solution(...) that returns the answer.

Key rule: use return — not print(). The grader only checks the returned value; anything you print is ignored.

✗ Won't be graded

def solution(a, b):
    print(a + b)

✓ Correct

def solution(a, b):
    return a + b

Your function is called with the challenge's test inputs, for example:

solution(3, 5)   # expects 8

Match the parameter names and count shown in the challenge description, and always finish with a return.
