Merge Sorted Arrays

Problem

Merge two individually sorted numeric arrays into one sorted array.

Examples

Example 1

Input: [[1,2,4],[1,3,5]]

Output: [1,1,2,3,4,5]

Example 2

Input: [[],[1,2]]

Output: [1,2]

Input and output use JSON-compatible values. For linked-list and tree questions, arrays represent the node structure as described above. Your code should implement solve(input).

How to solve Merge Sorted Arrays

One approach is: Use two pointers to compare the next available items. The reference code demonstrates this method. Compare the example and edge-case tests, then consider time and space usage.

Time and space complexity

Discuss the dominant operations and any additional data structures used by your implementation.

Practise and improve

Choose JavaScript, TypeScript or Python, complete the starter code, then select Run Tests. Request a hint when you need guidance, or choose View solution and confirm if you would like to study the reference implementation.
