Factorial of Big numbers [MEDIUM]

Company: Phillips, Microsoft, MAQ-Software, MakeMyTrip, BrowserStack  Question:  Given an integer, the task is to find factorial of the number.   Input: The first line of input contains an integer T denoting the number of test cases.   The first line of each test case is N,the number whose factorial is to be found   Output: Print the factorial of the number in separate line.   Constraints: 1 ≤ T ≤ 100 1 ≤ N ≤ 1000   Example: Input 3 5 10 2   Output 120 3628800 2 CODE:  import java.util.*; import java.lang.*; import java.io.*; import java.math.BigInteger; class Solution { public static void main (String[] args) { Scanner sc = new Scanner(System.in); int m = sc.nextInt(); for(int mi=0;mi<m;mi++){    int n = sc.nextInt();     BigInteger  fact= new BigInteger("1");    for(int i=1;i<n+1;i++){         fact= fact.multiply(BigInteger.valueOf(i...
