#include <iostream>
int main() {
using namespace std;
int a, b, buffer;
cin>>a>>b;
int *mass=new int[b];
int *deep=new int[33180];
for (int i4=0; i4<b; i4++) {
mass[i4]=0;
deep[i4]=1200;
}
for (int i5=b; i5<33180; i5++) {
deep[i5]=a;
}
for (int i6=0; i6<33180; i6++) {
for (int i9=1; i9<33180; i9++) {
if  (deep[i9-1]>deep[i9]) {
buffer=deep[i9-1];
deep[i9-1]=deep[i9];
deep[i9]=buffer;
}
}
}
mass[0]=a;
mass[b-1]=b;
for (int i=0; i<b; i++) {
for (int i2=1; i2<b; i2++) {
if  (mass[i2-1]>mass[i2]) {
buffer=mass[i2-1];
mass[i2-1]=mass[i2];
mass[i2]=buffer;
}
}
}
int sum=0;
for (int i3=0; i3<b; i3++) {
sum+=mass[i3];
}
cout<<sum;
delete []deep;
delete []mass;
return 0;
}

This solution works 1 second and output 1 if a=1 or b=1, and get AC!
