Let's go through the solution step by step:
We define a structure called box to represent the dimensions of a box. It has three members: length, width, and height.
We define a typedef for box to make it easier to use.
The get_volume() function takes a box as input and calculates the volume by multiplying its length, width, and height.
The is_lower_than_max_height() function takes a box as input and checks if its height is less than 41. It returns 1 if the condition is true and 0 otherwise.
In the main() function, we declare a variable n to store the number of boxes. We read the value of n from the user using scanf().
We dynamically allocate memory for an array of n boxes using malloc().
We use a loop to read the dimensions of each box from the user using scanf(). The dimensions are stored in the corresponding members of each box structure.
We iterate over the array of boxes and check if each box's height is lower than 41 using the is_lower_than_max_height() function. If true, we print the volume of the box using printf().
After the loop, we free the dynamically allocated memory for the array of boxes using free().
This solution reads the number of boxes and their dimensions, checks the height condition, calculates the volume, and prints the volume of boxes that satisfy the height condition.
Remember to handle input validation and error checking as necessary. Also, consider any additional constraints or requirements mentioned in the problem statement.
I hope this helps you understand and implement the "Boxes through a Tunnel" problem in C on HackerRank. Good luck with your coding!
