In cryptograms, each character is encoded into another. If the text is long enough, one can, as a strategy, use the frequency of occurrence of each char- acter. The most frequently occurring character will likely be the code for an e, because e is the most frequently used letter of the English alphabet. Design a class that attempts to determine the relative frequency of each letter by reading a file and keeping track of the number of times each of the 26 English alphabet characters appears. Also provide methods, such as highestFrequencyCharacter and lowestFrequencyCharacter. Test your class with a client program.

Problem B. Musical Key ConversionThe chromatic scale is a 12-note scale in music in which all notes are evenly spaced: that is, the ratio of the frequency between any two consecutive notes is constant. The notes are typically labeled in the following sequence: A, A#, B, C, C#, D, D#, E, F, F#, G, G# After G#, the labels loop back and start over with A (one octave higher). To convert between musical keys, you can shift all notes in a piece of music a constant number of steps along the scale above. For example, the sequence of notes E, E, F, G, G, F, E, D, C, C, D, E, E, D, D can be converted to another musical key by shifting everything up three steps: E, E, F, G, G, F, E, D, C, C, D, E, E, D, D G, G, G#, A#, A#, G#, G, F, D#, D#, F, G, G, F, F Notice that G was converted to A#, since going three steps up required us to loop off of the top of the scale back to the bottom: G -> G# -> A -> A#. Technically we should note that this would be A# of the next octave up, but we’ll…

Programming language: Dr. Racket Write a function encode that consumes a string message. The function produces a string which is encrypted according the following procedure: Only the letters from the original message will be encrypted. Other characters such as spaces, punctuation, numeric digits, etc. are not included in the encrypted message at all. The encrypted message will only contain uppercase letters. Each letter will be replaced by the uppercase letter at the opposite end of the English alphabet.In other words, A or a will become Z, B or b will become Y, C or c will become X, ..., Z or z will become A. The encrypted message will have a single space separating each letter. You may assume that the letters in message are English letters only. For example: > (encode "Cat") "X Z G" > (encode "Is this correct?") "R H G S R H X L I I V X G"
