  1. 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.

  2. The problem is that if you want the sum of the digits of a large number, not modulo anything, the tricks from number theory run out pretty quickly. Adding up the digits of a number doesn't mesh well with addition and multiplication with carries.

  3. 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.

  4. 26 gru 2023 · Given a number n, write code to find the sum of digits in the factorial of the number. Given n ≤ 5000. Examples: Input : 10. Output : 27. Input : 100. Output : 648. It is not possible to store a number as large as 100! under some data types so, idea is to store an extremely large number in a vector. 1) Create a vector to store factorial digits and.

  5. 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. factorialize =(num)=> {. if (num < 0) {. return -1; } else if (num == 0) {. return 1;
