A number that will be the same when it is written forwards or backwards is known as a Palindromic Number. For example, 1234321 is a palindromic number. All single digit numbers are palindromic numbers. Non-palindromic numbers can be paired with palin…

之前已经完毕了大整数的表示.绝对值的比較大小.取负值.加减法运算以及乘法运算. 详细见前两篇博客(自己动手写Java * ). 这里加入除法运算. 另外看到作者Pauls Gedanken在blog(http://paul-ebermann.tumblr.com/post/6312290327/big-numbers-selfmade-part-2-14-conversion-from)中的转换十进制数到大整数的方法,这里一并列出. 除法 除法使用经典的除法法则,可是有几个须要注意的问题,以下列…

自己用Java实现的大整数加减乘除运算.还有可以改进的地方,有兴趣的童鞋可以加以改进.仅供参考,请勿转载! package barrytest; import java.util.ArrayList;import java.util.List;import java.util.regex.Matcher;import java.util.regex.Pattern; //@author Barry Wang// all the four method have not considered th…
