。。本来以为会TLE，看了一下statu。。发现TLE的人不多，那就暴力了

#include <iostream>#include <cmath>using namespace std;int main() {int i, j;cin >> i >> j;int _max = 0, tmp, count;for(; i <= j; i++) {count = 1;tmp = i;while(tmp != 1) {if(tmp % 2 != 0)tmp = 3 * tmp + 1;else tmp /= 2;count++;}_max = max(_max, count);}cout << _max << endl;return 0;}
