Hello Programmers In this post, you will know how to solve the Small Factorials Codechef Solution.
One more thing to add, don’t directly look for the solutions, first try to solve the problems of Codechef by yourself. If you find any difficulty after trying several times, then you can look for solutions.
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())

x=nfact[k]*num + carry;
nfact[k]=x%10;
carry=x/10;
}
while(carry>0)
{
nfact[--j]=carry%10;
carry/=10;
}
num--;
}
for(int k=j;k<size;k++){
cout<<nfact[k];
}
cout<<endl;
}
return 0;
