题意:M×N的矩阵 让你保持每行每列的大小对应关系不变,将矩阵重写,重写后的最大值最小. 思路:离散化思想+并查集,详见代码 好题! #include <iostream> #include <string.h> #include <stdio.h> #include <algorithm> #include <cmath> #include <cstdlib> #include <bits/stdc++.h> using…

题目链接: http://codeforces.com/problemset/problem/650/C 题意: 给定n*m的矩阵,要求用最小的数表示每个元素,其中各行各列的大小关系保持不变. 分析: 将所有元素从小到大排序,然后找到每个元素相应位置进行填充,由于题目要求是每行每列的大小关系保持不变,所以填充的元素应为所在行和所在列中最大元素+1,保存好各行各列当前的最大值,并根据最后填充的元素不断更新就好啦. 问题是如何处理相同元素以及他们所在行列的更新. 这里使用并查集,将相同元素值的位置保…
