Clumsy Factorial - The factorial of a positive integer n is the product of all positive integers less than or equal to n. * For example, factorial (10) = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1.
4 paź 2024 · Problem: One day Anindya was experimenting with factorials. Anindya wanted to express $10!$ as the sum of factorial of some numbers in such a way that each number used is less than $10$. The factorial of the same number can be used more than once.
For example, factorial(10) = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1. We instead make a clumsy factorial: using the integers in decreasing order, we swap out the multiply operations for a fixed rotation of operations: multiply (*), divide (/), add (+) and subtract (-) in this order.
29 cze 2015 · E.g. factorial of 10! is 3628800 but how do I calculate it without using any sorts of calculator or calculate the numbers from 10 to 1? Thanks in advance!
Factorial Trailing Zeroes - Given an integer n, return the number of trailing zeroes in n!. Note that n! = n * (n - 1) * (n - 2) * ... * 3 * 2 * 1. Example 1: Input: n = 3 Output: 0 Explanation: 3! = 6, no trailing zero. Example 2: Input: n = 5 Output: 1 Explanation: 5! = 120, one trailing zero.
25 maj 2020 · I am doing euler problem where you need to find the sum of integers of a factorial number. so for example 10! is 3 + 6 + 2 + 8 + 8 + 0 + 0 = 27. I wrote this using big-int library to deal with large numbers.
