You'll learn a brief overview of this conversion and how binary strings are represented in computers. 1.Start with a non-negative decimal number n.2.If n is 0, return an empty list, as there are no binary digits to represent 0.3.Otherwise, divide n by 2 using integer division // to get the quotient q and the remainder r.4.Call the dec_to_bin function recursively with q as the input, and append the remainder r to the result.5.The base case of n being 0 will eventually be reached, at which point an empty list will be returned.6.As the recursive calls return, the remainders are accumulated in the result list, representing the binary digits of n.7.Once the final recursive call returns, the result list contains the binary representation of n, with the least significant digit at the end of the list.8.Return the result list. Reductive instead of oxidative based metabolism. Space Complexity:The space complexity of this algorithm is also O(log n), as the size of the recursive call stack is proportional to the number of times the input can be divided by 2 before reaching the base case.
