Python | Find Strong Numbers in given List of Numbers

Write a Python Program to find all the strong numbers among the given list of numbers. Write a function to find and return the factorial of a number. Use it to solve the problem.

Example of Strong Number:

N = 145=1!+4!+5! = 1+24+120 = 145

Hint: Sample list can be [145,375,100,2,10]

---

SOLUTION IN PYTHON

def factorial(number): if(number == 0 or number == 1): fact = 1 else: fact = number * factorial(number - 1) return fact def strong_number(list): new_list =[] for x in list: temp = x sum = 0 while(temp): rem = temp % 10 sum += factorial(rem) temp = temp // 10 if(sum == x): new_list.append(x) else: pass return new_list ls = [145,375,100,2,10] strong_num_list = strong_number(ls) print(strong_num_list)
