Please write the function in C

[15 points] Write a function that gets a linked list and a parameter k, and removes the k'th element from the end of the list. (For k-0, we need to remove the last element). For example, if the input list is 1- 2-3-+ 4- 5, and k 2, then after applying the function, the list will be 1-24-5. If k >= length of the list, then the list remains the same void LL remove kth from end (LL t* 1st, int k); [4 points] What is the running time of your function
