The permutationEquation function you provided seems to implement the permutation equation method in Python. This method takes a list p as input and returns a list of values based on the permutation equation.
Let's break down the code to understand how it works:
The function permutationEquation takes a list p as an argument.
It initializes an empty list called result to store the computed values.
It iterates over the range of indices of the input list p using the range function.
Inside the loop, it calculates p1 by finding the index of i+1 in p and adding 1 to it. The index function returns the index of the first occurrence of the specified value in the list.
Then, it finds the index of p1 in the list p using the index function again, and adds 1 to it.
The computed value is then appended to the result list.
After the loop completes, the function returns the result list.
This function essentially calculates the permutation equation p(p(y)) = x for each value x in the input list p and returns the resulting list.
Please note that the code assumes that the input list p is 1-based indexed (i.e., the values start from 1). If the input list is 0-based indexed, the code would need to be modified accordingly.
