CodeForces 489C (贪心) Given Length and Sum of Digits...,题意:找出m位且各个数位数字之和为s的最大和最小整数,不包括前导0(比如说003是非法的),但0是可以的。分析:这题是用贪心来做的,同样是m位数,前面的数字越大这个数就越大。所以写一个can(intm,ints)函数,来
http://codeforces.com/contest/489/problem/C 大数就是从最高位,能大就大;小数就是从最低位,能小就小,再处理下最高位为0的情况。 无结果无非一个sum太小,min全为0,一个sum太大,全为9还有剩 1publicclassMain {2publicstaticvoidmain(String[] args) {3Scanner io =newScanner(System.in);4intlen =...
