Answer:
void print2(int row) {
 for (int i = 0; i < row; i++) {
  char ch = 'a';
  char print = ch;
  for (int j = 0; j <= i; j++) {
  	cout << print++;
  }
  cout << endl;
 }
}
int count_digits(int num) {
 int count = 0;
 int temp = num;
 while (temp != 0) {
  temp = temp / 10;
  count++;
 }
 return (num % count);
}

Answer:
Java program is explained below
Explanation:
import java.util.HashSet;
import java.util.Map;
import java.util.TreeMap;
public class TruckRace1 {
    public static HashSet<String> getPIDs (Map<String,String>nameToPID ){
        HashSet<String> pidSet = new HashSet<>();
        for(String ids: nameToPID.values()){
            pidSet.add(ids);
        }
        return pidSet;
    }
    public static void main(String[] args) {
        Map<String,String> pids = new TreeMap<>();
        pids.put("John","123");
        pids.put("Jason","124");
        pids.put("Peter","125");
        pids.put("Alice","126");
        pids.put("Peny","129");
        HashSet<String> ids = getPIDs(pids);
        for(String id:ids){
            System.out.println(id);
        }
    }
}
