एल्गोरिदम
Begin function AlexanderBogomolny() to implement the Algorithms Arguments: Val[] = an array N = number of elements taken as input. K = level Body of the function: intialize l = -1 l = l+1 Val[k] = l if (l == N) Call function display(Val, N) else for i = 0 to N-1 if (Val[i] == 0) Call AlexanderBogomolny(Val, N, i) l = l - 1 Val[k] = 0 End
