Vasya is very upset that many people on the Net mix uppercase and lowercase letters in one word. That's why he decided to invent an extension for his favorite browser that would change the letters' register in every word so that it either only consisted of lowercase letters or, vice versa, only of uppercase ones. At that as little as possible letters should be changed in the word. For example, the word HoUse

在數學中，矩陣是一個按照長方陣列排列的複數或實數集合，最早來自於方程組的係數及常數所構成的方陣。這一概念由19世紀英國數學家凱利首先提出。 矩陣是高等代數學中的常見工具，也常見於統計分析等應用數學學科中。在物理學中，矩陣於電路學、力學、光學和量子物理中都有應用；電腦科學中，三維動畫製作也需要用到矩陣。 矩陣
