Going by the above code, let's first start with the generateNextRow function. pascal triangle code kata . Change replace with this in your else condition: @zale already explained the problem with your for loop, no need to repeat that. When a control structure interrupts the flow of a program like return does in your program, do not use elif or else. Not Pascal language related. Here is the recursive function in question, without the second function to append the rows (I really wanted 1 all inclusive function anyway): To be clear, I have already completed the assigned task, this is just to provide a deeper understanding of recursion You just need to pass a list of lists through the recursion, and pick off the last element of the list (i.e. A-143, 9th Floor, Sovereign Corporate Tower, We use cookies to ensure you have the best browsing experience on our website. Below is the implementation of the above approach: C++ Java Python3 C# Javascript This method can be optimized to use O(n) extra space as we need values only from previous row. You've made a few confusions in the loop that builds a new line. Could you have done it without use of conv? with more readable and more meaning variable names.
