随机数大法

#include <iostream>
#include <stack>
#include <cmath>
#include <time.h>
#include <stdlib.h>
#include <vector>
#include <string.h>
#include <queue>
#include <stdio.h>
#include <iomanip>
#include <cstdio>
#include <algorithm>
#define LL long long
#define double long double
using namespace std;
const int N = 1e5 + 10;
const int INF = 0x3f3f3f3f;
signed main()
{
	int minn = 0, maxx = 1;
    int n;;
    cin >> n;
	srand((unsigned)time(NULL));
	int ans;
    while(n--)
    {
        ans = (rand() % (maxx - minn + 1)) + minn;
    }
    if(ans == 1)
    {
        puts("Yes");
    }
    else
    {
        puts("No");
    }
	return 0;
}

其实很简单，善用STL

思路

使用string类型自带的比较功能进行比较。

ACCODE

#include<bits/stdc++.h>
using namespace std;
int n;string a[205],b[205];
int main(){
    cin>>n;getchar();
    for(int i=1;i<=n;i++)getline(cin,a[i]);
    for(int i=1;i<=n;i++)getline(cin,b[i]);
    for(int i=1;i<=n;i++){
        if(a[i]!=b[i]){
            cout<<"No";return 0;
        }
    }
    cout<<"Yes";
    return 0;
}

#include<iostream>
#include<string>
#include<cstring>
using namespace std;
string a[1001],b[1001];
int main(){
    int n;
    cin>>n;
    getline(cin,a[0]);
    for(int i=1;i<=n;i++){
    	getline(cin,a[i]);
	}
    for(int j=1;j<=n;j++){
    	getline(cin,b[j]);
	}
	for(int i=1;i<=n;i++){
		int x=a[i].size();
		int y=b[i].size();
	//	cout<<a[i]<<" "<<b[i]<<endl;
		if(x!=y){
			cout<<"No";
			return 0;
		}
		for(int j=0;j<x;j++){
			if(a[i][j]!=b[i][j]){
			//	cout<<a[i][j]<<" "<<b[i][j]<<endl;
				cout<<"No";
				return 0;
			} 
		}
	}
	cout<<"Yes";
}
