Name Math::Permute::Lists - Generate all the permutations of zero or more nested lists. Synopsis use Math::Permute::Lists; permute {say "@_"} [1,2],[3,4]; # 1 2 3 4 # 1 2 4 3 # 2 1 3 4 # 2 1 4 3 # 3 4 1 2 # 3 4 2 1 # 4 3 1 2 # 4 3 2 1 permute {say "@_"} 1,[2,[3,4]]; # 1 2 3 4 # 1 2 4 3 # 1 3 4 2 # 1 4 3 2 # 2 3 4 1 # 2 4 3 1 # 3 4 2 1 # 4 3 2 1 Description Generate all the permutations of zero or more nested lists using the standard Perl metaphor. "permute()" returns the number of permutations in both scalar and array context. "permute()" is 100% Pure Perl. Export The "permute()" function is exported.
