Description

给三角形三条边，问这个三角形是直角，等腰，还是普通

Algorithm

先排序一下，然后判断

Code

#include <cstdio>
#include <iostream>
#include <algorithm>
using namespace std;
void solve()
{
  int a[3];
  for (int i = 0; i < 3; i++)
    scanf("%d", &a[i]);
  sort(a, a+3);
  if (a[0] * a[0] + a[1] * a[1] == a[2] * a[2])
  {
    puts("good");
    return;
  }
  if (a[0] == a[1] || a[1] == a[2])
  {
    puts("perfect");
    return;
  }
  puts("just a triangle");
}
int main()
{
  int t;
  scanf("%d", &t);
  for (int i = 0; i < t; i++)
    solve();
}
