Understanding the Merge Process
The essence of merging two sorted lists is to compare elements from both lists one by one and append the smaller element to the result list. We continue this process until all elements from both lists are included in the result list, ensuring it remains sorted.
Setting Up Your Lists
First, you need two pre-sorted arrays. For example:
Writing the Merge Function
Create a function that takes two sorted arrays as parameters:
Executing the Merge
To merge the lists, call the
mergeSortedLists function with your sorted lists:
Tips for Optimizing the Merge
- Keep track of the current index in both arrays to avoid unnecessary iterations.
- Use a while loop to ensure that elements are compared as long as both arrays have unmerged items.
- After one list is exhausted, concatenate the remaining elements of the other list, as they are already sorted.
Handling Edge Cases
Consider the possibility of different length arrays or empty arrays. The function above accounts for these scenarios by using the spread operator to concatenate any remaining elements after the main while loop.
Testing Your Function
Always test the merge function with various list combinations to ensure its reliability:
