Background Morse code is a character encoding scheme created for telecommunication in the early 19th century. Morse code uses standardized sequences of two different signal durations called dots and dashes to represent letters and numbers. The Morse code representation of the 26 letters and numbers are shown in Figure 1 below. A dot duration is the basic unit of time in the code transmission whilst a dash is three times the duration of a dot. For a character of letter or number, the dots and dashes are separated by spaces where each space has the same duration as a dot. Each letter is separated by a space of three units of time, whereas, each word is separated by a space equal to seven units of time.

You and your team have decided to use binary sequences to represent the dots and dashes in the Morse code. A dot is represented by 'l' and a dash is represented by '111'. The space in between the dots and dashes in a character is represented by a 'o'. For example, the letter 'A' is represented as '10111' and 'S' is '10101'. The letters in a word are separated by '000' and the words are separated by '0000000'. For example, 'SOS' is coded as 101010001110111011100010101 . 'MY PET' is coded as '111011100011101011101110000000101110111010001000111 Qla In the morse decoder.m file, write a function file that accepts Morse code of a letter in the form of 1s and Os as input and returns the decoded letter as a string. The following function file header is provided: function (str_letter] - morse_decoder (code) Note: Your function is required to only decode the 26 letters.
