思路:

  • 题意:有两科重a,b kg的求,初始时候相距d距离,只受重力影响,试问t0时间后他们之间的距离。
  • 感情这就是个假物理题,我想着他们只受重力作用那距离可不是就不会变嘛,之间输出d不就行了。
  • 官方题解:

代码实现:

#include
#define endl '\n'
#define null NULL
#define ll long long
#define int long long
#define pii pair
#define lowbit(x) (x &(-x))
#define ls(x) x<<1
#define rs(x) (x<<1+1)
#define me(ar) memset(ar, 0, sizeof ar)
#define mem(ar,num) memset(ar, num, sizeof ar)
#define rp(i, n) for(int i = 0, i < n; i ++)
#define rep(i, a, n) for(int i = a; i <= n; i ++)
#define pre(i, n, a) for(int i = n; i >= a; i --)
#define IOS ios::sync_with_stdio(0); cin.tie(0);cout.tie(0);
const int way[4][2] = {{1, 0}, {-1, 0}, {0, 1}, {0, -1}};
using namespace std;
const int  inf = 0x7fffffff;
const double PI = acos(-1.0);
const double eps = 1e-6;
const ll   mod = 1e9 + 7;
const int  N = 2e5 + 5;

int T, a, b, d, t;

signed main()
{
    IOS;

    cin >> T;
    while(T --){
        cin >> a >> b >> d >> t;
        cout << d << endl;
    }

    return 0;
}
