code for decomposition a permutation into a product of transpositions

Правка en1, от Hot_Potato, 2020-09-01 20:25:48

Given a list of strings lst and a list of integers p, reorder lst so that every lst[i] gets placed to p[i]. I am trying to solve this by decomposing permutation p into a product of transposition(swaps) and then use those swaps to reorder lst.. can anyone give me the code for decomposing a permutation into a product of transpositions?
