You are working for the military deciphering codes hidden in matrices by the enemy. You have figured out that the enemy hides important values starting at the 2nd value in each column and skipping every 4 elements down each column. This continues for every third column starting at the first column. It's discovered that if the found value is less than 15 then it corresponds to a zero otherwise, it corresponds to a one. Have your function output a vector of ones and zeros which correspond to the important values found in the matrix in the correct order.
