WebThanks to recursion, the Python code needed to sum the values of a nested number list is surprisingly short: def recursive_sum(nested_num_list): sum = 0 for element in nested_num_list: if type(element) == type( []): sum = sum + recursive_sum(element) else: sum = sum + element return sum WebYour solution must use recursion. In the example above, you need to add the characters "aborb" to "sing" to get "absorbing", and you need to add "ontrs" to "cat" to get "contrast". The letters in the string you return should be in the order you have to add them from left to right.
