Step 3. Creating and Changing Arrays
Exercises on creating, changing, and filling arrays.
Step 4. In-Place Operations
In-place operations. Changing arrays in place without extra memory.
Step 5. Advanced Level
Advanced array exercises.

Step 3. Creating and Changing Arrays

In this step you will learn to create new arrays, change existing ones, and perform operations that require careful index handling. The exercises help you understand how to change array structure and correctly process elements during shifts and replacements.

What you will learn:

Duplicate elements while respecting array length limits
Merge two arrays into one while preserving order
Replace elements based on values to the right
Move elements inside an array with shifting

Step 3. Creating and Changing Arrays

Duplicate Zeros
Merge Sorted Array
Replace Elements with Greatest on Right
Move Zeroes
