CodeForces 1353 B. Two Arrays And Swaps 2. 解读 将a序列按照升序排序, 将 b按照降序排序。 依次遍历 a序列中的所有元素,当 a_i > b_j时,将 a_i和b_j交换,然后j = j + 1。 3. 代码 #include <algorithm> #include <iostream> #include <string.h> const long long num = 1e2 + 1; using...
Codeforces Round #642 (Div. 3) B. Two Arrays And Swaps You are given two arrays aa and bb both consisting of nn positive (greater than zero) integers. You are also given an integer kk . In one move, you can choose two indices ii and jj (1≤i,j≤n1≤i,j≤n ) and swap aiai...
Two Strings Swaps 分类讨论 http://codeforces.com/contest/1006/problem/D 解题思路: 1.按照题目要求对字符串进行分割,分组讨论,每组得到四个字符,例如:上面串的第一个和最后一个,下面串的第一个和最后一个。 2.分类讨论: 一组字符中存在两对相等字符的情况则不需要替换操作 一组字符中上面两个与下面两个...
Professor doesn't want to make more than two swaps. Find the minimal value v and some sequence of no more than two swaps that will lead to the such value v. Professor makes swaps one by one, each new swap he makes with the new arrays a and b. Input The first line contains integer...

【Codeforces 1006D】Two Strings Swaps,【链接】"我是链接,点我呀:)"【题意】题意【题解】注意只能改变a不能改变b然后只要让a[i],b[i],a[ni1],b[ni1]这4个字符能凑成两对、全都一样就可以了分类讨论下就好【代码】cppincludedefinelllonglongusingnam
