题目描述: 解题思路: 反转的方法很简单,重点在于判断溢出的问题,下面给出了两种方法. Java代码: 方法一: 判断溢出方法:在执行完int newResult=result*10+tail语句后,紧接着进行逆运算result=(newResult-tail)/10,如果出现溢出,那么逆运算后result和newResult必然不相等,反之,如果没有溢出,则逆运算后result=newResult. public class LeetCode7 { public static void mai…

public class ReverseInteger { public static int reverse(int x) { long ret = 0; //如果是个位数,直接返回. if(x/10 == 0) return x; //循环的时候要循环商,因为会有例如302,20这样的含有0的情况. while(x!=0)//条件别携程x/10!=0;要看循环体里面最后的结果. { int mod = x%10; ret = ret*10 + mod; //要判断溢出的情况,比如输入1123…
