題目

How to Smolensk

定義一個結構體存名字和速度，按速度排序輸出

標程

#include<bits/stdc++.h>
using namespace std;
struct node{
	string name;
	long long speed;
}a[100001];
long long n,l;
bool cmp(node a,node b){
	return a.speed<b.speed;
}
int main(){
	ios_base::sync_with_stdio(false);
	cin.tie(0);
	cin>>n>>l;
	for(int i=0;i<n;i++)cin>>a[i].name>>a[i].speed;
	sort(a,a+n,cmp);
	for(int i=0;i<n-1;i++)cout<<a[i].name<<" "<<(i+1)*a[i].speed/l<<" "<<l-((i+1)*a[i].speed%l)<<endl;
	cout<<a[n-1].name<<endl;
	return 0;
}

也很簡單
