Tips:可以先将输入的字符串全部转化为小写字母,然后再将元音字母变为大写,时间复杂度O(n) #include<stdio.h> #include<string.h> #include<ctype.h> int main() { int T; scanf("%d",&T); getchar(); while(T--) { ]; gets(ch); //先全部变为小写字母 ;j<strlen(ch);j++) { ch[j] = tol…

题意:n个字符串,如果元音就是输出大写,否则输出小写. 析:没啥可说的,只要判断AEIOU就OK了. 代码如下: #include <iostream> #include <cstdio> #include <algorithm> #include <queue> #include <vector> #include <cstring> #include <map> #include <cctype> usin…

在上篇,我了解了基数的基本概念,现在进入Linear Counting算法的学习. 理解颇浅,还请大神指点! http://blog.codinglabs.org/articles/algorithms-for-cardinality-estimation-part-ii.html 它的基本处理方法和上篇中用bitmap统计的方法类似,但是最后要用到一个公式: 说明:m为bitmap总位数,u为0的个数,最后的结果为n的一个估计,且为最大似然估计(MLE). 那么问题来了,最大似然估计是什么东东…
