Output

Sure, here's a C version of your Python program. Please note that C doesn't have a direct equivalent to Python's list comprehension, so we'll have to initialize the multi-dimensional arrays manually. Also, C doesn't have a direct equivalent to Python's append function for arrays, so we'll use a dynamic array to store the taken lines.

This C code should mimic the behavior of your Python program. However, please be aware that this code assumes that the input array `arr` is already allocated and filled with data, and that the `size` and `lines_left` parameters are valid. Also, the code uses dynamic memory allocation, so you should free the memory used by the dynamic array when you're done with it to avoid memory leaks.

Output

Sure, here's a C version of your Python program. Please note that C doesn't have a direct equivalent to Python's list, so we'll use dynamic memory allocation for the multi-dimensional arrays. Also, C doesn't have a built-in function to return a list, so I've used a function to print the taken lines.

This C code follows the same logic as your Python code. It first allocates memory for the multi-dimensional arrays `dp` and `how`, then fills them according to the rules of your problem. After that, it prints the taken lines. Finally, it frees the allocated memory to prevent memory leaks.

Please note that this C version does not return the `taken_lines` list like the Python version does, but it is stored in an array called `taken_lines`. To return this value, you would need to create a new data type to hold both the minimum cost and the taken_lines list. Also, the memory allocated for `taken_lines` is freed after use to avoid memory leaks.
