HDU-1163Eddy's digital Roots,九余定理的另一种写法！

下午做了NYOJ-424Eddy's digital Roots后才正式接触了九余定理,不过这题可不是用的九余定理做的.网上的博客千篇一律,所以本篇就不发篇幅过多介绍九余定理了: 但还是要知道什么是九余定理: 九余数定理一个数对九取余后的结果称为九余数. 一个数的各位数字之和相加后得到的<10的数字称为这个数的九余数(如果相加结果大于9,则继续各位相加) 简单的说就是:一个整数模9的结果与这个整数的各位数字之和模9的结果相同: 以前做题不知道有这个定理一般暴力就过了,求数位和也不复杂,只不过更…

HDOJ 1163 Eddy's digital Roots 九余数定理+简单数论

我在网上看了一些大牛的题解,有些知识点不是太清楚, 因此再次整理了一下. 转载链接: http://blog.csdn.net/iamskying/article/details/4738838 http://www.2cto.com/kf/201405/297531.html 题目描述:求n^n次的digital root(数根),例如root(67)=6+7=root(13)=1+3=4; 一类解法: 求解思路:现在分析一个问题,假设将十位数为a,个位数为b的一个整数表示为ab,则推导得ab…
