## Problem

Chef is taking his baby steps into the world of programming.

The very first program he's tasked to write is as follows:
"Given two integers  and , print �+�."

Unfortunately, Chef makes a typo: his program outputs �×� instead of �+�.

Given the values of  and , can you help Chef find the absolute difference between the correct answer and the value his program prints?

### Input Format

The only line of input will contain two space-separated integers,  and .

### Output Format

Print a single integer: the difference between the correct answer and Chef's output.

1≤�,�≤10

### Sample 1:

Input

Output

4 7
17

### Explanation:

The correct answer is 4+7=11, but Chef's program prints 4×7=28.
The difference between them is ∣28−11∣=17.

## Code Examples

### #1 Code Example with C Programming

Code - C Programming

 #include<bits/stdc++.h>
using namespace std;
using ll = long long;

void solve()
{
int a,b,r;
cin>>a>>b;
r=abs(a*b-(a+b));
cout<<r<<endl;
}
int main()
{
ios_base::sync_with_stdio(false);
cin.tie(nullptr);

int TC = 1;
//cin >> TC;
//cin.ignore();
while (TC--) solve();
