# Date:             October 30th, 2024
# Description:      This program determines the winner(s) 
    of a rock collecting game, considering there are 3 participants.
    The input for each participant is an integer for the number of rocks that 
    they collected, and a string for their name. The program will then output 
    WHO (could be one to three winners) won the game - that is, whoever collected the 
    most rocks. Invalid inputs, such as negative numbers, will automatically assign 
    to 0 rocks. Also, the program will print out the average number 
    of rocks collected(still considering invalid numbers as 0). 
    The program will always print a welcome and exit statement.
# Input:            Strings person1, person2, and person3 : names of three 
                    participants. User input variable
                    Ints rocks1, rocks2, rocks3: the amount of rocks that each person 
                    collected. User input variable. Assigned value of 0 if inputted 
                    less than 0.
# Output:           One of three winner string output messages:
                    1. userMsg2 as string = [1st place person] is in first place!
                                            [2nd place person] is in second place.
                                            [3rd place person] is in third place.
                    2. userMsg3 as string = [ties first place person] and [other 
                                            tied 1st place person] are tied for first place.
                                            [2nd place person] is in second place!
                    3. userMsg4 as string = It is a three way tie!
                    avgRocks as double = Contains avg num of rocks collected for the NUM_PEOPLE
                    amnt of people. Always prints to the second dec point.
