有道云笔记处理小工具

有道云笔记中的数学公式插入比较烦人, 转换成markdown比较麻烦,用这个代码进行转换能稍微好一点.

#include<locale>
#include<iostream>
#include<string>
#include<cstdio>
using namespace std;

int main() {
    freopen("ans.out", "w", stdout);

    bool flag = false;
    while(getline(cin, s)) {
        int zz = s.size() + 1;
        s2.clear();
        for(int i = 0; i + 1 < zz;) {
