CodeForces 791A Bear and Big Brother

题目链接：http://codeforces.com/contest/791/problem/A
题意：给你一个a，一个b，a每天都乘3，b每天都乘2，问你几天后a超过b
解析：a,b都不大，直接模拟即可

#include <cstdio>#include <cstring>#include <algorithm>#include <cmath>#include <iostream>using namespace std;const int maxn = 2e5+100;int main(){    int a,b;    int ans = 0;    scanf("%d %d",&a,&b);    while(a<=b)    {        a *= 3;        b *= 2;        ans++;    }    printf("%d\n",ans);    return 0;}
