27. (a) Calendar Use Excel to create a spreadsheet of 365 rows and 2 columns, where the first column of each row contains a date in 2015 and the adjacent second column contains the corresponding day of the week. Figure 5.33 shows the first two rows of the spreadsheet. The remaining entries of the spreadsheet can be obtained by select- ing the cells in Fig. 5.30 and dragging them down until 365 rows have been created. (b) Save the spreadsheet as a CSV file named Calendar2015. csv. Note: Select "CSV (Comma delimited)(*.csv)" in the "Save as type" dropdown box. (c) Change the file's name to Calendar2015.txt. (d) Use the text file in a program that requests a date in 2015 as input and then gives its day of the week. See Fig. 5.31. Enter a date in 2015: 11/3/2015 11/3/2015 falls on a Tuesday A B 1 1/1/2015 Thursday 2 1/2/2015 Friday FIGURE 5.30 Spreadsheet for Exercise 27. FIGURE 5.31 Possible outcome of Exercise 27.

Question 1 (35 marks) Two friends are exchanging messages through regular post mail. They don't want anyone to understand their messages in case anyone read them. The messages are in the form of an array of characters, where each character has a numeric value as illustrated in the below lookup table. A В D E F G H J K M 2 3 4 10 11 12 13 1 7 8 N PQR S TU V w X Y 14 15 16 | 17 18 19 20 21 22 23 24 25 26 They decided to change the characters in the array in a way that cannot be observed by any accidental reading. They do so as follows: 1- Given the original message, for example: GREETINGS 2- transform the original character to its numeric value 7 18 5 5 20 9 14 7 19 3- For each number, subtracting from its value the value of the first lower value character after it, and if there's no such character they will keep that character without any change. 2 13 5 5 11 2 7 7 19 7 18 5 5 20 9 14 7 19 2 13 5 5 11277 19 7 18 55 20 9 14 7 19 7-5 = 2 7 18 55 20 9 14 7 19 18-5 = 13 7 18 55 20 9 14 7 19…

A matrix is a rectangular or square grid of numbers arranged into rows and columns.
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…
Python program code to find the degree distribution of the graph in Fig. 10.1 and plot this distribution is given below. The Degree_Dist function inputs the adjacency matrix of a graph, finds the degrees of each vertex by multiplying this matrix with the unity vector U in lines 10–12. The number of vertices with the same degree is calculated and stored in vector C in lines 17–20. Each element of this vector is divided by the number of vertices to find P(k) for k = 0, ..., n − 1 and finally this function is plotted against vertex degrees using the Python library mat plotlib.pylot.
