# Task 1: Consecutive Odds
# You are given an array of integers.
# Write a script to print 1 if there are THREE consecutive odds in the given array otherwise print 0.
#
# Example 1
# Input: @array = (1,5,3,6)
# Output: 1
#
# Example 2
# Input: @array = (2,6,3,5)
# Output: 0
#
# Example 3
# Input: @array = (1,2,3,4)
# Output: 0
#
# Example 4
# Input: @array = (2,3,5,7)
# Output: 1
