Question

易语言的超级模块识图怎么使用？为什么准确找图找到的？

Answer 1

#include <iostream>
#include <string.h>
#include <stdio.h>

using namespace std;
const int N = 1005;

int a[N],tmp[N];
int ans;

void Merge(int l,int m,int r)
{
int i = l;
int j = m + 1;
int k = l;
while(i <= m && j <= r)
{
if(a[i] > a[j])
{
tmp[k++] = a[j++];
ans += m - i + 1;
}
else
{
tmp[k++] = a[i++];
}
}
while(i <= m) tmp[k++] = a[i++];
while(j <= r) tmp[k++] = a[j++];
for(int i=l;i<=r;i++)
a[i] = tmp[i];
}

void Merge_sort(int l,int r)
{
if(l < r)
{
int m = (l + r) >> 1;
Merge_sort(l,m);
Merge_sort(m+1,r);
Merge(l,m,r);
}
}

int main()
{
int n,T,tt=1;
scanf("%d",&T);
while(T--)
{
scanf("%d",&n);
for(int i=0;i<n;i++)
scanf("%d",&a[i]);
ans = 0;
Merge_sort(0,n-1);
printf("Scenario #%d:\n%d\n\n",tt++,ans);
}
return 0;
}
