# "Suppose you're on a game show, and you're given the choice of three doors: Behind one 
# door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who 
# knows what's behind the doors, opens another door, say No. 3, which has a goat. He then 
# says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice?"
#
# Input Description
# On standard console input, you will be given a single integer ranging inclusively from 1 
# to 4,294,967,295 (unsigned 32-bit integer). This integer is the number of times you should 
# simulate the game for both tactics. Remember that a single "game simulation" is your program 
# randomly placing a car behind one door and two goats behind the two remaining doors. You must 
# then randomly pick a door, have one of the two remaining doors open, but only open if it's
# a goat behind said door! After that, if using the first tactic, you may open the picked door, 
# or if using the second tactic, you may open the other remaining door. Keep track if your 
# success rates in both simulations.
# 
# Output Description
# On two seperate lines, print "Tactic 1: X% winning chance" and "Tactic 2: Y% winning chance", 
# where X and Y are the percentages of success for the respective tactics
# 
# Sample Input
# 1000000
#
# Sample Output
# Tactic 1: 33.3% winning chance
# Tactic 2: 66.6% winning chance
