// 1) c) You generated a fibonacci sequence of a certain length, starting with 1 and 1. Your friend does not like even numbers, so starting from the first number, everytime he encounters an even number, he deletes that number as well as the previous number. Output the new sequence.

// Length of original sequence: 8
// 1 3 13 21

// (The original sequence is 1, 1, 2, 3, 5, 8, 13, and 21.)
