解题思路:因为给定的数据是多组,所以我们只需要多次做加法就可以了,将上一次的和又作为下一次加法运算的一个加数. 反思:还是题意理解不够清楚,最开始以为只是算三个大数相加,后来才发现是多个,然后注意到当输入a的第一个字符为0的时候结束运算,输出结果.  Integer Inquiry  One of the firstusers of BIT's new supercomputer was Chip Diller. He extended his explorationof powers of 3…

问题: 大数相加不能直接使用基本的int类型,因为int可以表示的整数有限,不能满足大数的要求.可以使用字符串来表示大数,模拟大数相加的过程. 思路: 1.反转两个字符串,便于从低位到高位相加和最高位的进位导致和的位数增加: 2.对齐两个字符串,即短字符串的高位用‘0’补齐,便于后面的相加: 3.把两个正整数相加,一位一位的加并加上进位. 具体代码如下: /** * 用字符串模拟两个大数相加 * @param n1 加数1 * @param n2 加数2 * @return 相加结果 */ pu…

之前参加某公司笔试,机试题目是大数相加,两大数是字符串形式,求和. 当时讨巧用的是BigDecimal类,但是发迷糊了,以为b1.add(b2)后,和就加到b1上了,结果一直输出不对. 其实应该是这样: private static void add2Sum(String s1, String s2) { System.out.println("-----------"); BigDecimal b1 = new BigDecimal(s1); BigDecimal b2 = new…

之前杭电上也做过a + b的高精度的题,不过这道题的区别是有多组数据. 之前做的时候开了3个字符数组a,b,c,在计算的时候还要比较a,b长度,短的那个还要加'0',还设置了一个add来存放进位. 现在看来这种算法确实很繁琐. 而这次只用了两个字符数组,一个放加数,一个放和. 相比之前程序更短小了,而且可读性也提高了. 果然办法都是逼出来的. 没有了add,在判断进位的时候就看那一位的ASCII码是否>'9',然后进位. 尤其需要注意的一点是可能会出现连续进位的情况,比如99999 + 1.解决…

最近写了一个大数相乘和相加的程序,结果看起来是对的.不过期间的效率可能不是最好的,有些地方也是临时为了解决问题而直接写出来的. 可以大概说一下相乘和相加的解决思路(当然,大数操作基本就是两个字符串的操作了): 一.思路: 在操作大数前,一定会有一些异常判断,比如输入的字符串是否合法(是否是纯数字?是否为空?等等),然后才是具体的操作实现: 1.大数相加(大体思路:将大数相加问题,转换成十以内的两数相加): ①申请合适的空间,一般可以认定,两个数字相加时,长度至多是最长的数的长度或最长的数的长度加…
