A + B

Description

Given two integers A and B, the expression is: each three digits are separated by commas.
Calculate the result of A + B and output it in the normal form.

Input

The input contains multiple groups of data. Each group occupies one row and consists of two integers A and B-10 ^ 9 <A, B <10 ^ 9 ).

Output

Calculate the result of A + B and output it as normal. Each group of data occupies one row.

Sample Input

-234,567,890 123,456,789
1,234 2,345,678

Sample Output

-111111101
2346912

The Code is as follows:

# Include <iostream>

# Include <string>

Using namespace std;

Int main ()

{

String a1, a2;

While (cin> a1> a2 ){

Int l1 = a1.size ();

Int l2 = a2.size ();

Int x1, x2;

X1 = x2 = 0;

Int f = 1;

For (int I = 0; I <l1; I ++)

{

If (a1 [I] = '-') {f =-1; continue ;}

If (a1 [I]! = ','){

X1 = x1 * 10 + a1 [I]-'0 ';

}

}

X1 = x1 * f;

F = 1;

For (int I = 0; I <l2; I ++ ){

If (a2 [I] = '-') {f =-1; continue ;}

If (a2 [I]! = ','){

X2 = x2 * 10 + a2 [I]-'0 ';

}

}

X2 = x2 * f;

Cout <x1 + x2 <endl;

}

// System ("pause ");

Return 0;
