太闲了的我

#include<bits/stdc++.h>
using namespace std;
int a,b;
int check(int middle){
	if(middle >= a+b){
		return 1;
	}
	return 0;
}
int main() {
	cin>>a>>b;
	int l = INT_MIN,r = INT_MAX;
	int ans;
	while(l <= r){
		int mid = (l+r)/2;
		if(check(mid)){
			l = mid+1;
			ans = mid;
		}
		else{
			r = mid-1;
		}
	}
	cout<<ans;
    return 0;
}

有很大的问题
