codeforce 1311 D. Three Integers

In one move, you can add +1 or −1 to any of these integers (i.e. increase or decrease any number by one). You can perform such operation any (possibly, zero) number of times, you can even perform this operation several times with one number. Note that you cannot make non-positive numbers using such operations.

You have to perform the minimum number of such operations in order to obtain three integers A≤B≤C such that B is divisible by A and C is divisible by B.

You have to answer t independent test cases.

Input
The first line of the input contains one integer t (1≤t≤100) — the number of test cases.

The next t lines describe test cases. Each test case is given on a separate line as three space-separated integers a,b and c (1≤a≤b≤c≤104).

Output
For each test case, print the answer. In the first line print res — the minimum number of operations you have to perform to obtain three integers A≤B≤C such that B is divisible by A and C is divisible by B. On the second line print any suitable triple A,B and C.

纯暴力枚举(有点技巧，小剪枝）

#include <bits/stdc++.h>
using namespace std;
const long long maxn = 1e15 + 5;
int main()
{
    int t;
    cin >> t;
    while (t--)
    {
        long long a, b, c, a1, b1, c1;
        scanf("%lld %lld %lld", &a, &b, &c);
        long long cnt = maxn;
        for (long long k = 1; k <=5*c; k++)
        {
            for (long long  i = 1;  i*k<=5*c; i++)
                for (long long  j = 1;i*k* j <=5*c ; j++)
                {

                    long long temp = abs(k - a) + abs(i * k - b) + abs(j * i * k - c);
                    if (temp < cnt)
                    {
                        cnt = temp;
                        a1 = k;
                        b1 = i * k;
                        c1 = i * j * k;
                    }
                   // else
                      //  break;
                }
        }
        printf("%lld\n", cnt);
