I have my code below and I am stuck at the last part which is the display of the thread that finished first and last. There are times when it give the correct output and sometimes it is not. How can it be fixed?

![Create a program that allOws users to enter the number of voters, then
generates 3 Threads.
Thread #1 will be named Candidate #1, Thread #2 as Candidate #2 and Thread #3 as
Candidate #3.
Each of the thread runs an iterative statement that generates "x" random numbers
between 1 to 3.
If the system generates a value of 1, that means a vote will be counted for
Candidate #1; if 2 vote will be added for Candidate #2 otherwise, it will be
credited to Candidate#3.
Note:
1. "x" (will be based on the "Number of voters")
2. If either of candidates have the same number of votes, then output text must say
"No Winner"
Sample output:
Enter # of voters: 3
Voter 1 Thread #1 = 1
