编程打印数字1-9的乘法表。编写一个字符界面的Application程序，接受用户输入的10个整数，比较并输出其中的最大和最小值。　　编程接受用户输入的任意多个整数，以-1标志输入的结束，求出其中的最大值、最小值和平均值。　　编写程序实现如下功能，接受用户输入的一个1-9000之间的年份，输出这一年是否是闰年。-Print digital programming of the multiplication table 1-9. The preparation of a character of the Application Interface process, to accept user input 10 integer, to compare the output of the largest and the minimum value. Programmed to accept user input of any number of integer to-1 marks the end of input, which obtained the maximum, minimum and average. Programming to achieve the following functions, to accept a user input between 1-9000 years, whether or not output this year is a leap year.
