Hello, I would like to ask about the solution to Two sums. My idea is just to return i,j which goes trough for cycles as indices. def two_sum(L, target): for i in range(len(L)): for j in range(i+1, len(L)-1): result = L[i] + L[j] if result == target: return [i, j] return -1 What I don't understand is why should we used a dictionary in the solution of this exercise. Does it bring any benefit? Thanks, Best, Maros J
