FLOW018 Problem - CodeChef : problem statement.
CodeChef: Practical coding for everyone : link to my solution.
Can anyone tell me why am I getting wrong answer? I checked the code many times, but it wasn’t helpful.
for(int y = 0 ; y < (n-1) ; y++){
n--;
fact_num = fact_num*n;
}
isn’t doing what you think it is doing, you’re decrementing n and incrementing y at the same time. Also you don’t need an array to store the results. I guess after checking the code down below, you’ll probably understand what you’ve done wrong (The solution is in C because I don’t like C++).
#include<stdio.h>
int main(){
int t;
scanf("%d",&t);
long n;
long res;
while(t--){
res=1;
scanf("%ld",&n);
if(n!=0){
for(;n>0;n--){
res*=n;
}
}
else{
res=1;
}
printf("%ld\n",res);
}
}

You can do this . it works for me
t = int(input())
n = []
for i in range(t):
x = int(input())
n.append(x)
for i in range(t):
a = n[i]
fact = 1
while a>0:
fact = fact * a
a = a - 1
print(fact)
