题意:给出了N个数字,确定一个尽可能大的数字E,要求这N个数字中大于E的数字有E个. 思路: 乍一看不知道题目在说啥.静下心来多读几遍题目,在草稿纸上比划比划,发现是个大水题.解释一下样例,原始序列为6 7 6 9 3 10 8 2 7 8,将其从大到小排序,则是10 9 8 8 7 7 6 6 3 2,(假设下标从1开始),我们这样来理解,第1天骑行10公里(说明有1天超过1):第2天骑行9公里(说明有2天超过2):第3天骑行8公里(说明有3天超过3)...,第6天骑行7公里(说明有6天超过6…

思路:搞懂题意是关键–E满足有共有E天骑车的距离超过E米,求最大的E! 将数组排序,我们假设最大的E是e,e满足条件有e天骑车超过e米,并且e+1不满足有e+1天骑车超过e+1米.那么我们可以逆序统计所有满足的就是答案. AC代码 #include <stdio.h> #include <algorithm> using namespace std; const int maxn = 1e5 + 5; int a[maxn]; int main() { int n; scanf(&…
