全WA，自己下测试点试没问题

#include <bits/stdc++.h>
using namespace std;
int main()
{
	int abc[3];
	cin >> abc[0] >> abc[1] >> abc[2];
	if (abc[0] > abc[1])
		swap(abc[0], abc[1]);
	if (abc[0] > abc[2])
		swap(abc[0], abc[2]);
	if (abc[1] > abc[2])
		swap(abc[1], abc[2]);
	char ABC[3];
	cin >> ABC;
	cout << abc[ABC[0] - 65] << " "; 
	cout << abc[ABC[1] - 65] << " ";
	cout << abc[ABC[2] - 65] << endl;
	return 0;
}
