[code removed - moderator]

I am cofused and not understanding, what exactly should be the first argument for the function linear_activation_backward() when we want to find the values of dA_prev_temp, dW_temp, db_temp for multiple layers (activation function is ‘relu’). Here as the for loop is going in reversed direction so i guess for lth layer it should be dA[l-1] but it is giving me error, so i kept dA[l]. (so that l=L-1 in the first iteration which means it takes dA[L-1] computed from the last-layer where sigmoid activation is applied).Please correct me where i am wrong.
