测试十万个数,极为保险!!!!!
但真正AC代码链接——————大神代码#include <iostream> #include <cstdio> #include <cstdlib> #include <cmath> #include <cstring> #include <algorithm> using namespace std; int main() { int i,n,a[100001],b,m=0; scanf("%d",&n); for(i=1;i<=n;i++) { if(i<=100000) scanf("%d",&a[i]),m++; else getchar(); } sort(a+1,a+1+m); printf("%d",a[m/2]); return 0; }

krew的方法,快膜
var n,s,ans,i,x:longint;
begin
read(n);
s:=0;
ans:=23333;
for i:=1 to n do
begin
read(x);
if ans=x then inc(s)
else
if s=0 then begin s:=1;ans:=x;end
else dec(s);
end;
write(ans);
end.这种做法的前提是菊花数>n/2
但是十分耗时科莫多龙
PS:本题与codevs上 FFF 团卧底的菊花 完全一样

晕,看来这题数据结构要求挺严格啊,明天用堆试试,
嘛,靠运气算是勉强AC了- -(其实是懒得花时间想,pia~)等我明天有空好好想想再完美AC一次- -话说这种题目数据那么弱,试几下运气刚好就能过了

随机取中间的100个数 输出出现次数最多的那个。。竟然神奇的AC了
```Pascalvar
a,b:array[1..100]of longint;
i,j,n,id,ans,mid,x,max:longint;begin
randomize;
readln(n);
mid:=random(n-100);
if mid>0 then
begin
for i:=1 to mid do read(x);
max:=100;
end
else max:=n;
for i:=1 to max do read(a[i]);
for i:=1 to max do
for j:=1 to max do
if a[j]=a[i] then inc(b[i]);
for i:=1 to max do
if b[i]>ans then
begin
id:=i;
ans:=b[i];
end;
writeln(a[id]);
end.
```
随机化交了三遍 都AC

这个方法很简单。
就是开个a[99]的数组,a[0]代表个位数为0,a[1]代表个位数为1,a[10]代表十位数为0,以此类推。
然后就读入n个数,每个数拆成10位,对每一位直接加就可以啦。#include<stdio.h>
using namespace std;int a[100]={},n,x,i,j;
bool ok;int main(){
scanf("%d",&n);
ok=false;
for(i=1;i<=n;i++){
scanf("%d",&x);
j=0;
while(j==0||x!=0){
a[x%10+j*10]++;
x/=10;j++;
}
}
for(i=99;i>=0;i--){
if(a[i]>=(n+1)/2&&(ok||i%10!=0||i==0)){
ok=true;printf("%d",i%10);
}
}
return 0;

/*
此题巧妙利用了要求数一定出现超过一半,节约空间一个个数读入,用k来记录个数,
运用+ -对消的方法求出出现最多的数
注意一定要用scanf读入不然完美超时

k++;
else if(k==0)
x=a,k++;

测试数据 #0: Accepted, time = 0 ms, mem = 712 KiB, score = 10
测试数据 #1: Accepted, time = 0 ms, mem = 712 KiB, score = 10
测试数据 #2: Accepted, time = 0 ms, mem = 712 KiB, score = 10

测试数据 #9: Accepted, time = 281 ms, mem = 716 KiB, score = 10
对每个数据段进行取样,每次选取最大的几个, 最后把选到最多的数输出,话说为什么我用了6*20000的数组要用这么多空间??…… -

和判断一些数中是否有一个出现大于一半一样
int main()
{
int pre, next, n, cnt = 0;
scanf("%d", &n);
scanf("%d", &pre);
for (int i = 0; i < n - 1; i++)
{
scanf("%d", &next);
if (pre == next) cnt++;
else
{
if (cnt == 0) pre = next, cnt++;
else cnt--;
}
}
printf("%d\n", pre);
return 0;
}
