#include <iostream> #include <cmath> using namespace std; int main(){ int testcase; while(cin >> testcase){ int length; for(int i = 0 ; i < testcase ; i++){ cin >> length; double sum = 0; double *scores = new double[length]; int count = 0; for(int j = 0 ; j < length ; j++){ cin >> scores[j]; sum = sum + scores[j]; } double avg = sum / length; for(int j = 0 ; j < length ; j++){ if(scores[j] > avg){ count++; } } printf("%.3f%%\n",count * 100.0 / length); } } }
