Task4. ASCII code is a seven-bit code in which the decimal digits are represented by the BCD code preceded by 011. • Since it is a 7-bit code, it represents 2^7 =128 symbols. • The letter of the alphabet and other symbols and instructions are represented by other code combination as shown in Table 1.9.6. For example, ASCII code for N = (4 E) H (1001110) binary. A quick exercise for you here, Write the ASCII code for 'ELECTRONICS'.

The language used for the code is fortran 2008. Thank you 1. There are many algorithms that can be used to encrypt a message. One of these algorithms can be described as follows: • Choose a “code word”. For example, “fortran”. • Assign integer values to each of the characters in the code word corresponding to their placement in the alphabet. In the case of the code word “fortran”, the integer values would be (6, 15, 18, 20, 18, 1, 14). • Change each character in the message to be encrypted by adding the code word values determined above (in order) to each of the characters in the message to be encrypted. The code word is reused as many times as necessary. For example, suppose that we want to encrypt the message “hello”, we would first determine the integer values for each character in the message (8, 5, 12, 12, 15). Each of these values would be modified by adding the code word values, ie. (8+6, 5+15, 12+18, 12+20, 15+18) = (14, 20, 30, 32, 33). The resulting values are then translated…
A-1D-9 Given the code segment below, what will be the sum of ALL elements of dCData after running the codes? Limit your answer to one (1) decimal place only if answer is a floating point number. int main() int i; double dAData[3] = {1.e, 2.0, 3.0}; double dBData[3] = {4.e, 5.0, 6.0}; double dCData[3]; for (i = e; i < 3; i++) dCData[i] = dAData[i] + dBData[2-i] +i * i; return e; Assume the necessary libraries and functions are included and implemented. Write INVALID (in all CAPITAL LETTERS) if it is an invalid access, or if the task will cause a syntax or logical error.
PLEASE CODE IN PYTHON Crypto Columns The columnar encryption scheme scrambles the letters in a message (or plaintext) using a keyword as illustrated in the following example: Suppose BATBOY is the keyword and our message is MEET ME BY THE OLD OAK TREE. Since the keyword has 6 letters, we write the message (ignoring spacing and punctuation) in a grid with 6 columns, padding with random extra letters as needed: MEETME BYTHEO LDOAKT REENTH Here, we've padded the message with NTH. Now the message is printed out by columns, but the columns are printed in the order determined by the letters in the keyword. Since A is the letter of the keyword that comes first in the alphabet, column 2 is printed first. The next letter, B, occurs twice. In the case of a tie like this we print the columns leftmost first, so we print column 1, then column 4. This continues, printing the remaining columns in order 5, 3 and finally 6. So, the order the columns of the grid are printed would be 2, 1, 4, 5, 3, 6, in…
code in java pls Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Find the smallest value, and then subtract it from all three values, thus removing the gray.
Part 2: Binary Arithmetic One of the most common operations we perform on binary numbers (and all numbers) is addition. It can be cumbersome to convert your binary numbers to decimal just to add them and convert them back, so instead we will be learning how to add binary numbers directly. Binary addition works the same way as decimal addition, with the added restriction that each digit can only go up to 1. Let's consider the possibilities for adding the values of any 2 single digits together: 0 + 0 0 + 1 1 + 0 1 + 1 0 1 1 10 (remember that 10 in binary represents the number 2) In that last case, the result is larger than a single digit. When adding larger binary numbers, that means we have to carry the 1 over to the next column. This presents us with another new case: what happens if we have 1 + 1 + carried 1? In that case, the result is 11, which means that column's result is 1, and we carry 1 to the next column. Below is an example of adding two binary numbers that shows all…
Numbers between 0 and 15 are stored in the memory location starting from physical address B000Fh randomly. Write a program which finds the element order number in the string starting from 0 to 15 and writes to physical address C000Fh. (Eg: "1" is 2nd element in the first string, "2" is 4th element, ....etc)
Part 3: Negative Binary Numbers This standard method of binary number representation doesn't account for negative numbers. We can't just throw a negative sign in front of a binary number though - everything in a computer must be represented by 1's and 0's. One way we can get around this is by using the very first digit of each binary number to represent the sign: 0 for positive and 1 for negative. This is called 1's complement representation. 00010110 -> 0 0010110 -> positive 22 10010110 -> 1 0010110 -> negative 22 Using 1's complement representation we can represent the numbers -127 through 127 in a single byte (note that we can only go half as high as an unsigned number because half of the possible representations for that byte are being used for the negative numbers). However, there is a flaw with 1's complement: the representation of the number 0. 00000000 -> 0 0000000 -> zero 10000000 -> 1 0000000 -> negative zero? Because of this, we…
Part IV An early method of telegraph communication was based on the Morse code. This code uses patterns of short and long pulses to represent a message. Each letter is represented as a sequence of dots (a short pulse), and dashes (a long pulse). For example, the first eight letters of the alphabet have the following representation: A In HDL Verilog В C D E F G H Design and implement a circuit that takes as input one of the first eight letters of the alphabet and displays the Morse code for it on a red LED. Your circuit should use switches SW2-o and pushbuttons KEY1 a user presses KEY1, the circuit should display the Morse code for a letter specified by SW2-0 (000 for A, 001 for B, etc.), using 0.5-second pulses to represent dots, and 1.5-second pulses to represent dashes. Pushbutton KEY, should function as an asynchronous reset. A high-level schematic diagram of the circuit is shown in Figure 2. (1-0 as inputs. When Hint: Use a counter to generate 0.5-second pulses, and another counter…
PYTHON: In order to beat AlphaZero, Grandmaster Hikaru is improving her chess calculation skills.Today, Hikaru took a big chessboard with N rows (numbered 1 through N) and N columns (numbered 1 through N). Let's denote the square in row r and column c of the chessboard by (r,c). Hikaru wants to place some rooks on the chessboard in such a way that the following conditions are satisfied:• Each square of the board contains at most one rook.• There are no four rooks forming a rectangle. Formally, there should not be any four valid integers r1, c1, r2, c2 (≠r2,c1≠c2) such that there are rooks on squares (r1,c1), (r1,c2 (r2,c1)and (r2,c2).• The number of rooks is at least 8N.Help Hikaru find a possible distribution of rooks. If there are multiple solutions, you may find any one. It is guaranteed that under the given constraints, a solution always exists.InputThe first line of the input contains a single integer T denoting the number of test cases. The first and only line of each test case…
