Python recursive function:
Given an ordered list L. A permutation of L is a rearrangement of its elements in some order. For example (1,3, 2) and (3, 2, 1) are two different permutations of L=(1,2,3). Implement the following function: def permutations (lst, low, high) The function is given a list 1st of integers, and two indices: low and high (lows high), which indicate the range of indices that need to be considered The function should return a list containing all...
