Using this information, construct another markov chain which is capable of indicating whenthe solar heat must be augmented

A solar heating device can recharge in a single sunny day enough to provide for the next two days. In other words, the only times that the solar heat must be augmented by some other heat source is when there are three or more consecutive cloudy days. During the heating sea- son, a period of 120 days, the weather patterns are described by the following Markov Chain
