You are given a list lst.
Return a new list that is lst rotated one position to the left: the first element moves to the end, and every other element shifts one place toward the front.
For example, [1, 2, 3, 4] becomes [2, 3, 4, 1].
If the list is empty, return an empty list [].
NOTE: This is a function-type question — you only write the function. Do not read input or print anything; a hidden checker calls your function and checks its return value.
Arguments
[1, 2, 3, 4]
Returns
[2, 3, 4, 1]
