Strengths:

• The solution correctly implements the dynamic programming approach.
• The time complexity is optimal (O(n)), which is better than the reference solution.
• The code is readable and well-structured.

Areas for Improvement:

• The space complexity can be optimized to O(1) by using variables to store only the previous row's costs instead of a full dp table.
• The condition checks for j could be simplified. For example, instead of checking j == 0, j == 1, j == 2, you could use a more concise approach like using modulo arithmetic or a loop.
• The initial value of mini (100000) is arbitrary. It would be better to use INT_MAX or a similar constant to ensure it works for all possible inputs.
