Morse code messages are composed of two types of signals, a dot and a dash. Suppose that it takes 1 time unit to transmit a dot and 2 time units to transmit a dash.
Problem: Compute the total number Sn of different Morse code messages (message=any string of dots and dashes) that can be sent in n time units? To solve this problem, complete the following steps:
1.Show that S1=1, S2=2, S3=3, S4=5 by just listing all of the possible messages in each case.
2.Explain why the following recurrence relation holds for Sn:
Sn = Sn1 + Sn2 for n > 2
