LEARN Theory for this problem

+

These exercises combine arithmetic, comparisons, and small branches. Keep each condition explicit and easy to verify.

Connection to “Nearest of Two”: here, intermediate values are best kept in named variables so the formula stays readable and data types remain clear.

#include <iostream>
#include <cstdlib>
using namespace std;
int main() {
    long long x,a,b;
    cin >> x >> a >> b;
    cout << (llabs(x-a)<=llabs(x-b)?a:b) << '\n';
    return 0;
