Hello coders, today we are going to solve Small Factorials Codechef Solution. Which is a part of Codechef Solution.
Problem
You are asked to calculate factorials of some small positive integers.
Input
An integer t, 1<=t<=100, denoting the number of testcases, followed by t lines, each containing a single integer n, 1<=n<=100.
Output
For each integer n given at input, display a line with the value of n!
Example
Sample Input
4 1 2 5 3
Sample Output
1 2 120 6

def factorial(n):
if n == 0:
return 0
elif n == 1:
return 1
else:
return n * factorial(n - 1)
n = int(input())
for i in range(n):
num = int(input())

carry=x/10;
}
while(carry>0)
{

carry/=10;
}
num--;
}
for(int k=j;k<size;k++){
cout<<nfact[k];
}
