题目链接: Hdu 5439 Aggregated Counting 题目描述: 刚开始给一个1,序列a是由a[i]个i组成,最后1就变成了1,2,2,3,3,4,4,4,5,5,5.......,最后问a[i]出现n次(i最大)时候,i最后一次出现的下标是多少? 解题思路: 问题可以转化为求a[i] == n (i最大),数列前i项的和为多少. index: 1 2 3 4 5 6 7 8 9 10 a:        1 2 2 3 3 4 4 4 5 5 可以观察出:ans[1] = 1,…
思路: 利用java 特性,将数字从1 一直加到n,全部放到String中,然后依次对strring扫描每一位,使其carr[str.charAt(i)-'0']++; 最后输出carr[i],即可. 13 string=12345678910111213 carr[1]++.carr[2]++.carr[3]++....carr[1]++.carr[1]++.carr[1]++.carr[2]++.carr[1]++.carr[3]++ AC Code: import java.util.Sc…

1.题目大意 把前n$(n\le 10000)$个整数顺次写在一起:12345678910111213……计算0~9各出现了多少次. 2.思路 第一想法是打表,然而觉得稍微有点暴力.不过暂时没有想到更好的办法了,写完看了一下其它人的思路好像也差不多是打表的思路. 3.应注意的问题 (1)首先是格式问题,我第一次提交的时候PE了,因为没有意识到空格也会有影响.最开始我的最后一段代码是: for(i=0;i<10;i++) printf("%d ",s[n][i]); printf(…
题目:https://nanti.jisuanke.com/t/41412思路:dfs           先取ai>2  2^12>3000 因此至多取11个 其余用1补           (3000*2)-(3000+2)=2998 那么需要加入2998个1 正好3000位 所以 3000是ai最大取值           计算ans时 有重复元素的排列组合 :如1112233 res=7!/(3!*2!*2!)           另外预处理阶乘及其逆元 #include<bit…
