# Author: AKHILESH SANTOSHWAR

# this program will illustrate an example for finding the longest CONTINUOUS ODD subsequence

# INPUT: [2, 6, 8, 3, 9, 1, 5, 6, 1, 3, 5, 7, 7, 1, 2, 3, 4, 5]
# OUTPUT: [1, 3, 5, 7, 7, 1] 6

# in short we have to find the elements and length of the longest continuous odd subsequence
