allan 方差（阿伦方差）是David AIlan于1966年提出的，最初该方法是用于分析振荡器的相位和频率不稳定性，高稳定度振荡器的频率稳定度的时域表征目前均采用Allan方差。由于陀螺等惯性传感器本身也具有振荡器的特征，因此该方法随后被广泛应用于各种惯性传感器的随机误差辨识中。(Allan variance (Allen variance) was proposed by David Allan in 1966. Initially this method was used to analyze the phase and frequency instability of oscillators. The time-domain characterization of the frequency stability of high-stability oscillators is currently based on Allan variance. Since gyros and other inertial sensors also have the characteristics of oscillators, the method is subsequently widely used in the random error identification of various inertial sensors.)

Problem Description 对于输入的每个字符串，查找其中的最大字母，在该字母后面插入字符串“(max)”。 Input 输入数据包括多个测试实例，每个实例由一行长度不超过100的字符串组成，字符串仅由大小写字母构成。 Output 对于每个测试实例输出一行字符串，输出的结果是插入字符串“(max)”后的结果，如果存在多个最大的字母，就在每一个最大字母后面都插入"(max)"。

Sqlite3 的确很好用。小巧、速度快。但是因为非微软的产品，帮助文档总觉得不够。这 些天再次研究它，又有一些收获，这里把我对 sqlite3 的研究列出来，以备忘记。(Sqlite3 really good use. Small, fast. But for the Microsoft products, always feel that not enough to help document. This Some day to study it, and have some harvest, here I study on SQLite3 list, to forget.)
