能帮我看看这个二分查找错在那里吗

**#include
#include

using namespace std;
int main()
{
int x,y;
cout << "请输入数组长度";cin >> x;
vector a{};
a.resize(x);
cout << "请输入数组元素\n";
for (int i=0 ; i<x;i++)
{
```
  cin >> a[i];
```
}
for(int o=0;o<x;o++)
{
```
  for (int i = o; i <x; i++)
  {
      if (a[o]>a[i])
      {
          swap(a[o], a[i]);
      }
  }
```
}
for (int i : a)
{
cout << i<<" ";
}
cout << '\n' << "请输入你要查找的数";
cin >> y;
int min = 0, max = x-1;
int m = (min + max) / 2;
if (a[m] == y)
```
  cout << "找到了在数组中
```

第" << (x - 1) / 2 << "位";
else
{

  while (min <= max)
  {
      if (a[m] > y)
      {
          max = m - 1;
      }
      if (a[m] < y)
      {
          min = m + 1;
      }
      if (a[m] = y)
      {
          cout << "找到了在数组中第" << m+1 << "位";
          break;
      }
      if (a[m]!=y)
      {
          cout << "没找到";
          break;
      }

  }

}
}**

请正确的插入代码，你这样根本看不到你的代码
