# Challenge: Birthday Cake Candles - HakerRank
# Author: Stella Miranda

# Colleen is turning n years old! Therefore, she has n candles of various heights on her cake, and candle i has height height_i .
# Because the taller candles tower over the shorter ones, Colleen can only blow out the tallest candles.
# Given the height_i for each individual candle, find and print the number of candles she can successfully blow out.

# Input Format
# The first line contains a single integer, n , denoting the number of candles on the cake. 
# The second line contains n space-separated integers, where each integer i describes the height of candle i.

# Constraints
# 1 <= n <= 10^5
# 1 <= height_i <= 10^7

# Output Format
# Print the number of candles Colleen blows out on a new line.

# Sample Input 0
