Problem:
Score : 100 points

Problem Statement

Compute A \times B.

Constraints

1 \leq A \leq 100

1 \leq B \leq 100

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A B

Output

Print the value A \times B as an integer.

Sample Input 1

2 5

Sample Output 1

10

We have 2 \times 5 = 10.

Sample Input 2

100 100

Sample Output 2

10000

Solution in C# (Mono-csc 3.5.0) (judge verdict: Accepted)

using System;
					
public class Program
{
	public static void Main()
	{
		//ulong N = ulong.Parse(Console.ReadLine());
		string[] str = Console.ReadLine().Split(' ');
		//int[] arr = new int[1000000];
		ulong A = ulong.Parse(str[0]);
		ulong B = ulong.Parse(str[1]);
			
		/*
		for(ulong i=0; i<N; i++){
			if(arr[ulong.Parse(str[i])] == 0){
				cnt++;
				arr[ulong.Parse(str[i])]=1;
			}else{
				cnt2++;
			}
		}
		*/
		
		Console.WriteLine(A*B);
		
	}
}
 
public class Sol
{
	public double Solve(ulong A, ulong B, ulong x)
	{
		double ans;
		double tmp1 = (A*x)/B;
		double tmp2 = x/B;
		
		tmp1 = Math.Truncate(tmp1);
		tmp2 = Math.Truncate(tmp2);
		
		ans = tmp1 - (A*tmp2);
		
		return ans;
