Permutations 1 X48980
Some genome rearrangements change the order of the nucleotides in a nucleic acid sequence, resulting in a permutation of the nucleic acid sequence. For example, TATATA is a frequent rearrangement of TATAAT. An interesting problem is the generation of all the permutations of a genomic sequence of length n.
Write code for the permutations problem. The program must implement and use the PERMUTATIONS function in the pseudocode discussed in class, which is iterative and is not allowed to perform input/output operations. Make one submission with Python code and another submission with C++ code.
Input
The input is a string s over the alphabet Σ={A,C,G,T}.
Output
The output is a sorted list of all the permutations of s, without repetitions.
Hint
There are at most n! permutations of a genomic sequence of length n.
