Iahub is a big fan of tourists. He wants to become a tourist himself, so he planned a trip. There are n destinations on a straight road that Iahub wants to visit. Iahub starts the excursion from kilometer 0. The n destinations are described ... | instruction | 0 | 108,168 | 1 | 216,336 |
Tags: combinatorics, implementation, math
Correct Solution:
```
def gcd(a,b) : return a if b==0 else gcd(b,a%b)
n = int(input())
l = input().split()
l = [int(i) for i in l]
l.sort()
t = sum((i+i-n+1)*l[i] for i in range(n))
t = t+t+sum(l)
d = gcd(t,n)
print(t//d,n//d)
