- 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.We usually write numbers in decimal form (or base 10), meaning numbers are composed using 10 different “digits" {0,1, ...,9}. Sometimes though it is useful to write numbers hexadecimal or base 16. Now there are 16 distinct digits that can be used to form numbers: {0, 1,...,9, A, B, C, D, E, F}. So for example, a 3 digit hexadecimal number might be 2B8. Assume that digits and letter can be repeated. a. How many 4-digit hexadecimals are there in which the first digit is E or F? b. How many 5-digit hexadecimals start with a letter (A-F) and end with a numeral (0-9)?We usually write numbers in decimal form (or base 10), meaning numbers are composed using 10 different "digits" {0,1,...9}. Sometimes though it is useful to write numbers hexadecimal or base 16. Now there are 16 distinct digits that can be used to form numbers: {0,1,....,9,A,B,C,D,E,F}. So for example, a 3 digit hexadecimal number might be 2B8. a. How many 4-digit hexadecimals are there in which the first digit is E or F? b. How many 5-digit hexadecimals start with a letter (A-F) and end with a numeral (0-9)? c. How many 2-digit hexadecimals start with a letter (A-F) or end with a numeral (0-9) (or both)?
- 7. We usually write numbers in decimal form (or base 10), meaning numbers are composed using 10 different "digits" {0,1,.9). Sometimes though it is useful to write numbers in hexadecimal or base 16. Now there are 16 distinct digits that can be used to form numbers: {0,1,..,9,A,B,C,D,E,F}. So, for example, a 3 digit hexadecimal number might be 3B8. (a) How many 2-digit hexadecimals are there in which the first digit is E or F? Explain your answer in terms of the additive principle (using either events or sets). (b) Explain why your answer to the previous part is correct in terms of the multiplicative principle (using either events or sets). Why do both the additive and multiplicative principles give you the same answer? (c) How many 3-digit hexadecimals start with a letter (A-F) and end with a numeral (0-9)? Explain. (d) How many 3-digit hexadecimals start with a letter (A-F) or end with a numeral (0-9) (or both)? Explain.Python only Rajesh loves lucky numbers. Everyone knows that lucky numbers are positive integers whose decimal representation contains only the lucky digits 4 and 7. For example, the numbers 47,744, 4 are lucky and 5, 17,467 are not. Let Fa(x) equal the number of digits d in the decimal representation of the positive integer x. Chef is only interested in F4(x) and F7(x) functions. For a given positive integer N, he wants to know the total number of distinct pairs (L; R) such that F4(L) + F4(L + 1) + ... + F4(R) equals F7(L) + F7(L + 1) + ... + F7(R) and 1caleulator Create four-function. 4. f using fallowing for fractions by foomu20s Addilion: alb + cld = (a'd + b'c)/(6'd). %3D Subtraction: a/b - cld = (a*d- b'c) |(b"d).

For example, the 3x3 matrix 1 2 3 45 6 7 8 9 can be row-wise represented as ([1,2,3,4,5,6,7,8,9], 3), where the number3 represents the number of columns in the matrix. Similarly, 1 35 24 6 becomes ([1,3,5,2,4,6], 3). A submatrix can be defined as an (1,r,t,b) tuple, where 1 and r are left and right column indices, and t and b are top and bottom row indices (all inclusive). write a function that takes a tuple containing the list representing a matrix, and the column count of the matrix, along with another tuple representing a specific submatrix, and returns the list representation of the submatrix along with its column count as a tuple. For example, given submatrix(([1,2,3,4,5,6,7,8,9,10,11,12], 4), (1,2,0,1)) returns: ([2,3,6, 7], 2) because, ([1, 2,3,4,5,6,7,8,9,10,11,12], 4) represents: 2 3 4 5 6 7 9 10 11 12 8 and (1,2,0,1) represents the submatrix bet ween column indices 1 and 2 (both inclusive), and row…1. Determine |A|, where: {z} b. A = {{z}} _d. A = {z, {z}, {z, {z}}} _e. A = P({z}) _f. A = P({Ø,z}) a. A = _c. A = {z, {z}}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…array([[ 1960, 54211], [ 1961, 55438], [ 1962, 56225], [ 1963, 56695], [ 1964, 57032], [ 1965, 57360], [ 1966, 57715], [ 1967, 58055], [ 1968, 58386], [ 1969, 58726], [ 1970, 59063], [ 1971, 59440], [ 1972, 59840], [ 1973, 60243], [ 1974, 60528], [ 1975, 60657], [ 1976, 60586], [ 1977, 60366], [ 1978, 60103], [ 1979, 59980], [ 1980, 60096], [ 1981, 60567], [ 1982, 61345], [ 1983, 62201], [ 1984, 62836], [ 1985, 63026], [ 1986, 62644], [ 1987, 61833], [ 1988, 61079], [ 1989, 61032], [ 1990, 62149], [ 1991, 64622], [ 1992, 68235], [ 1993, 72504], [ 1994, 76700], [ 1995, 80324], [ 1996, 83200], [ 1997, 85451], [ 1998, 87277], [ 1999, 89005], [ 2000, 90853], [ 2001, 92898], [ 2002, 94992], [ 2003, 97017], [ 2004, 98737], [ 2005, 100031], [ 2006, 100832], [ 2007, 101220], [ 2008, 101353], [ 2009, 101453], [ 2010, 101669], [ 2011, 102053], [ 2012, 102577], [ 2013, 103187], [ 2014, 103795], [ 2015, 104341], [ 2016, 104822], [ 2017, 105264]]) Question 2 Now that we have have our…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…JAVA CODE PLEASE Functions with 1D Arrays Quiz by CodeChum Admin Instruction: Write a function that accepts two integers X and Y and prints the binary representation of the numbers starting from X to Y.
