题意:给两个整数,求这两个数的反向数的和的反向数,和的末尾若为0,反向后则舍去即可.即若1200,反向数为21.题目给出的数据的末尾不会出现0,但是他们的和的末尾可能会出现0. #include <iostream> #include <string.h> #include <stdio.h> #include <string> #include <string.h> using namespace std; int n1,n2;//n1表示a的…

/*Sample Input 3 24 1 4358 754 305 Sample Output 34 1998 */ 值得总结的几点就是: 1.atoi函数将字符串转化为整型数字(类似于强制转换) 2.sprintf函数的用法,比如sprintf(res,"%d",i+j); 3.这种将字符串逆置的方法应该是最简洁的 #include<iostream> #include <stdio.h> #include <stdlib.h> #include…

一.题目大意 反转两个数字并相加,所得结果崽反转.反转规则:如果数字后面有0则反转后前面不留0. 二.题解 反转操作利用new StringBuffer(s).reverse().toString();来实现,去0则利用while循环对10取余判断,对数取整.多次用到字符串和整数之间的互换,字符串转整数用到了 int num=Integer.parseInt(s);,整数转字符串则s= ""+a1;即可. 三.java代码 import java.util.Scanner; publi…
