题 题意 给你一个区间,求里面有多少个数是k的次方. 分析 暴力,但是要注意这题范围会爆long long,当k=1e8: l=1:r=1e18时 k²=1e16,判断了是≤r,然后输出,再乘k就是1e24 , ULL 都存不下,就爆了. 所以当 t > r / k 时跳出循环 代码 AC代码 #include <stdio.h> unsigned long long l,r,k,t; int ok; int main(){ scanf("%lld%lld%lld",…

Link Cut Tree 刚开始写了个指针版..调了一天然后放弃了.. 最后还是学了黄学长的板子!! #include <bits/stdc++.h> #define INF 0x3f3f3f3f #define full(a, b) memset(a, b, sizeof a) using namespace std; typedef long long ll; inline int lowbit(int x){ return x & (-x); } inline int read…
