[알고리즘] 백준 10872 : 팩토리얼 - B5

2023.04.07 풀이

1. 팩토리얼 내장함수

import sys
input=sys.stdin.readline
import math

n=int(input())
print(math.factorial(n))

2. 반복문

import sys
input=sys.stdin.readline

n=int(input())
res=1

for i in range(1, n+1):
    res*=i

print(res)

3. 재귀함수

import sys
input=sys.stdin.readline

n=int(input())

def factorial(n):
    if n<=1:
        return 1
    else:
        return n * factorial(n-1)

print(factorial(n))
