Space complexity of recursive factorial

Web31. jan 2024 · The code as written is awfully bad: If n > 0 then it makes two recursive calls calculating the exact same result, which would make it θ(n). That's awfully bad because it can easily be done in θ(log n) by making one call and multiplying the result by itself.. There is no reason to think this would be $θ(n^2)$. WebEach time the factorial function is called, 3 operations are performed- 1 comparison, 1 multiplication and 1 subtraction. Therefore, the time complexity can be analyzed as: T (n) …

Answer : The recursive function uses stack space and in this case, we are recursively calling the function until n reaches to 0 and that will create n stack frames in the memory. Can you draw the recursion tree for this case? 2. Iterative Solution

WebAfter the recursive call, we swap the elements back to their original positions to restore the original order of the subarray. The time complexity of the algorithm can be expressed as a recurrence relation: T(n) = n * T(n-1) = n! where T(n) represents the time taken to compute all permutations of a set of size n. The base case is T(1) = 1, since there is only one … Web29. jún 2015 · As Wikipedia says, quickSort needs O(log n) extra space when the following conditions are met:. In-place partitioning is used.
