<prompt> Andika kazi katika Python na utata wa wakati wa sababu O n.  <response>: Here is an example of a function in python with a factorial time complexity On!:def permutationlst: if lenlst 0: return elif lenlst 1: return lst else: res for i in rangelenlst: for j in permutationlst:i lsti1:: res.appendlsti j return resThis function takes a list as an input and returns a list of all possible permutations of the elements in the input list. The time complexity of this function is On! because it generates all possible permutations of n elements, which is n! possible combinations.
