Task 1: Consecutive Odds
Submitted by: Mohammad S Anwar

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
