完成对任意一个文本文件的字符统计工作。可以统计的信息有中文字符数、英文单词数、行数、字符个数（不计空格）和空格数。 (Calculate Chinese characters, English words the number of rows, number of characters (excluding spaces) and number of spaces in a txt file.)

Data Encryption by Matrix Multiplication We will only use numbers 0 to 26 for the encryptive mathematics operation. Numbers from 1 to 26 are for letters from A to Z and 0 is for all non-letter characters. To minimize usage of numbers, all letters are converted to upper case. The original message is converted to number array according to the ASCII table and minus 64. We partition whole array into blocks of 8 numbers. The last block may be added several zeros. Then multiply each block by the an 8x8 matrix A which is invertible in Z27 to get cipher data. The decryption is the same process except to use its inverse matrix B. For good visual reading, we convert all non-letter characters to under score for the decryption.

动态倒计时牌，目标时间（即倒计时截至时间）的年、月、日、时、分、秒以及倒计时主题可以根据不同主题由用户动态设定，并且在此设定基础上在屏幕上显示距离相关主题到达之时还有n年、n天和n秒（其中的三个n各不相同，且随着程序运行动态变化），以北京时间作为主要显示板块，同时显示纽约、伦敦时间的附加倒计时板块。程序中除了刚运行时给出一次当前标准时间值（或读出系统当前时间）外，在程序运行期间应在自己独立的用户时钟控制下，而不受外界输入影响和系统时间的束缚。(Dynamic countdown, the target time (ie, as the countdown time) of the year, month, day, hour, minute, second, and the countdown theme can set different themes by the users, and in this setting is displayed on the screen on the basis of distance-related There are n the theme of the time of arrival, n day n seconds (one of the three different n, and with the dynamic program runs), to Beijing as the main display section, also shows New York, London time, the additional countdown Plate. In addition to just run the program once the current standard time value is given (or read the current system time), but during the program should be independent in their own under the control of the user clock, and free from outside influence and input system time constraints. )
