题解——CF Manthan, Codefest 18 (rated, Div. 1 + Div. 2) T1(找规律)

就是找一下规律

但是奈何昨天晚上脑子抽

推错了一项QwQ

然后重新一想

A掉了QwQ

#include <cstdio>
#include <algorithm>
#include <cstring>
#include <cmath>
using namespace std;
int main(){
  int n;
  scanf("%d",&n);
  int i=1,ans=1,now=1;
  while(i<n){
    i+=now*2;
    now*=2;
    ans++;
  }
  printf("%d",ans);
  return 0;
}
