Write list functions that carry out the following tasks for a list of integers. Use the main function as test program Write a function named swap that swaps the first and last elements in the list. . Write a function named shift that shifts all elements by one to the left and move the first element into the last position. For example, [1, 2, 3, 4, 5] would be transformed into 12, 3, 4,5, 1]. Write a function named shift kthat shifts all elements k to the left and move the first k elements into the last k positions. For example, if the original list is [1, 2, 3, 4, 5], after calling shift_k(list, 3) the list becomes [4, 5, 1, 2, 3]
