![]() That means they are ordered by comparing their leftmost different characters. We have to use Recursion to achieve Back Tracking and with the help of Back Tracking, we are performing Brute Force.Below is the syntax highlighted version of Permutations.java def bitStr (n, s): if n 1: return s return digit + bits for digit in bitStr (1, s) for bits in bitStr (n - 1, s) print (bitStr (3, 'abc')) I'm pretty weak in algorithmic thinking and am struggling for both an intuitive understanding of this, as well as tracing it. If we have any procedure and, in that procedure, we want to go back and take another route then those procedures can be implemented using Recursion.
