Web13 Jan 2024 · Factorial can be understood as the product of all the integers from 1 to n, where n is the number of which we have to find the factorial of. Example: Input number: 5 Output: Factorial is: 120 Explanation: 1 * 2 * 3 *4 * 5 = 120 You may have noticed that the operation always remain same or we can say that its business logic never changes. WebThe recursion terminates when O [-i] is the empty set and it returns the value of zero or w is less than w (i). Basically, you start with the full set of possible objects. For each object you get its value and create the subproblem excluding that object and with the available max weight reduced by the excluded object's weight.
