1. 题目描述对于给定的$a, n, mod, a \in [2,11], n \in [0, 10^9], mod \in [1, 10^9]$求出在$[1, a^n]$内的所有$a$进制下的数并且不含重复数字. 2. 基本思路这题比赛的时候,没人做出来,但是基本思路大家都有.显然可以直接将$n$改写为$\min(n,a)$.我比赛的代码TLE,思路是这样的:首先$mod$很小时,可以数位DP解:当$mod$很大时,可以先找到所有的排列然后,然后令$delta = fact(a)/fact(a…

做leetcode的题 We are playing the Guess Game. The game is as follows: I pick a number from 1 to n. You have to guess which number I picked. Every time you guess wrong, I'll tell you whether the number is higher or lower. You call a pre-defined API guess…

好久没切 leetcode 的题了,静下心来切了道,这道题比较有意思,和大家分享下. 我把它叫做 "不一样的猜数字游戏",我们先来看看传统的猜数字游戏,Guess Number Higher or Lower.题意非常的简单,给定一个数字 n,系统会随机从 1 到 n 中抽取一个数字,你需要写一个函数 guessNumber,它的作用是返回系统选择的数字,同时你还有一个外部的 API 可以调用,是为 guess 函数,它会将你猜的数字和系统选择的数字比较,是大了还是小了. 非常的简单,…
