二叉搜索树绝对是最简单的做法！！新手们一定要来试一试（maybe）。

#include<bits/stdc++.h> using namespace std; int main(){ int a[3]; cin>>a[0]>>a[1]>>a[2]; sort(a,a+3); cout<<a[0]<<" "<<a[1]<<" "<<a[2]; return 0; }

#include<iostream> using namespace std; int main(){ int a,b,c; cin >> a >> b >> c; if(a>b){ swap(a,b); } if(b>c){ swap(b,c); } if(a>b){ swap(a,b); } cout << a << " " << b << " " << c; return 0; }

#include <bits/stdc++.h> using namespace std; int a[5]; int main(){ cin>>a[0]>>a[1]>>a[2]; sort(a,a+3); cout<<a[0]<<" "<<a[1]<<" "<<a[2]; return 0; }

#include <iostream> using namespace std; int a[4]; int main(){ for(int i=1;i<=3;i++){ cin>>a[i]; } for(int i=1;i<3;i++){ for(int j=1;j<=3-i;j++) { if(a[j]>a[j+1]){ swap(a[j],a[j+1]); } } } for(int i=1;i<=3;i++){ cout<<a[i]<<" "; } return 0; }

#include <bits/stdc++.h> using namespace std; bool cmp(int a,int b){ return a<b; } int main() { int a[3]={}; for(int i=0;i<3;i++) cin>>a[i]; sort(a,a+3,cmp); for(int i=0;i<3;i++) cout<<a[i]<<" "; }
