Let vec = [(“A”, “B”), (“A”, “C”), (“A”, “D”), (“B”, “C”), (“B”, “D”)] be a vector. I want to count the number of appearance of each element at each step in the for loop. function count_occurrences(vec) vect = [] nb_appear_A = 0 nb_appear_B = 0 nb_appear_C = 0 nb_appear_D = 0 …

Just replace your multitude of variables with a dictionary: function count_occurrences(vec) vect = [] nb_appear = Dict() for v in vec v1, v2 = v nb_appear[v1] = get(nb_appear, v1, 0) + 1 nb_appear[v2] = get(nb_appear, v2, 0) + 1 push!(vect, (nb_appear[v1…
