// your code goes here
Scanner s = new Scanner(System.in);
int n = s.nextInt();
int factorial = 1;
for(int i = n; i>= 1; i--) {
factorial = factorial * i;
}
System.out.println(factorial);
}

I use this try catch method but although this method removes NZEC , it does not provide any solution at all .Please resolve this issue someone.
Thanks, it’s working now. I guess java’s still tryna catch itself!
yeah both the answers are coming as wrong, it is very weird.

am too not able to submit my java code…getting NZEC error
I used try catch and fast I/O methods too
Before using nextInt() , use sc.hasNext()
inside if and true accept input and initialise every variable with default values
For example
int g = 0
if( sc.hasNext())
{
g = sc.nextInt();
}
// proceed using g
It helped…man
Yaa … U are correct
IN JAVA,
if ur error is in line where u take input then try in this format ,
Scanner sc=new Scanner(System.in);
int takingInput=0;
if(sc.hasNextInt()){
takingInput= sc.nextInt();
}
