题目链接:http://acm.hdu.edu.cn/userstatus.php?user=zhsl 题意:给两个大数,他们之间的加法法则每位相加不进位.现在可以对两个大数的每位重新排序,但是首位不能为0,求两个数相加最大的和. 从最高位开始,考虑和最大贪心,每次从两个大数中找两位a和b,max=(a+b)%10的和最大.如果max有多种组成情况,对于a+b<10的所有情况,我们任意选择一组就可以了.对于存在a'+b'>10的组合情况,如果有a+b<10的组合情况,我们就选择a+b&l…

题目的意思是给你两个数字(多达10^6位) 做加法,但是有一点,没有进位(进位不算,相当于这一位相加后对10取模) 你可以任意排列两个数字中的每一位,但是不能是0开头. 现在题目要求以这种不进位的算法计算得到的最大值是多少? 看完题目就会知道,这个题目一定不是dp,或者说根本不是什么高端的算法,那是什么呢? 对,你没有猜错——贪心. 为什么可以用贪心呢?我们比较一个数,都是从高位的先比较,所以只要高位的大,这个数就大:于是我们要得到最大的和,就要先统计能够构成多少个9,多少个8……(有大的就先构…
