hexadecimal 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. (d) How many 3-digit hexadecimals start with a letter (A-F) or end with a numeral (0-9) (or both)? Explain

Part 4: Hexadecimal Representation (Base 16) Another commonly used number system in computer science is hexadecimal, which is base 16. That means each digit has 16 possible values and the position of each digit going from right to left represents increasing powers of 16. In order to represent 16 possible values in a single digit, we use letters to represent the numbers greater than 9: A B C D E F 10 11 12 13 14 15 The process for converting a hexadecimal number to decimal is the same as for binary, just using powers of 16. Here is an example converting the number 1B7 to decimal: 1 B 7 256's place 16's place 1's place 16^2 16^1 16^0 (16^2 * 1) + (16^1 * 11) + (16^0 * 7) = (the letter B represents 11 as shown in the table above) (256 * 1) + (16 * 11) + (1 * 7) = 256 + 176 + 7 = 439 So the number 439 in hexadecimal is 1B7. You can also convert decimal to hexadecimal using the same division method as binary, except by dividing by 16. Remember to convert the…

#Solve it with C programing Mr. X is a student of Computer Science. He is facing a problem and needs your help to solve it.The problem is, you will be given N integer numbers( 4<n<=100) which are arranged side by side (x1,x2,x3,x4,.....).Now you have to sort those items in ascending order. After doing this , your job is to print the items in a sorted way and find the median.[NB: when N is odd , Median= (N+1)/2; When N is even Median= (N/2)+1 ] Sample Input: 74 7 11 2 9 3 5Sample Output:2 3 4 5 7 9 115
Sevens rule, zeros drooldef seven_zero(n):Seven is considered a lucky number in Western cultures, whereas zero is what nobody wants to be. We now bring these two opposites briefly together with positive integers that consist of some solid sequence of sevens, followed by some (possibly empty) solid sequence of zeros. Examples of such integers are 7, 77777, 7700000, 77777700, or 700000000000000. A surprising theorem proves that for any positive integer n, there exist infinitely many integers of such seven-zero form that are divisible by n. This function should return the smallest such seven-zero integer. This exercise is about efficiently generating all numbers of the constrained form of sevens and zeros in strictly ascending order to guarantee finding the smallest working such number. This logic might be best written as a generator to yield such numbers. The body of this generator consists of two nested loops. The outer loop iterates through the number of digits d in the current number.…

Sevens rule, zeros drool def seven_zero(n): Seven is considered a lucky number in Western cultures, whereas zero is what nobody wants to be. Let us briefly bring these two opposites together by looking at positive integers that consist of some solid sequence of sevens, followed by some (possibly empty) solid sequence of zeros. Examples integers of this form are 7, 77777, 7700000, 77777700, and 70000000000000. A surprising theorem proves that for any positive integer n, there exist infinitely many integers of such seven- zero form that are divisible by n. This function should return the smallest such seven-zero integer. Even though discrete math and number theory help, this exercise is not about coming up with a clever symbolic formula and the proof of its correctness. This is rather about iterating through the numbers of this constrained form of sevens and zeros efficiently and correctly in strictly ascending order, so that the function can mechanistically find the smallest working…

C Program to convert Decimal to Binary Decimal to binary in C: We can convert any decimal number (base-10 (0 to 9)) into binary number(base-2 (0 or 1)) by c program. Decimal Number Decimal number is a base 10 number because it ranges from 0 to 9, there are total 10 digits between 0 to 9. Any combination of digits is decimal number such as 23, 445, 132, 0, 2 etc. Binary Number Binary number is a base 2 number because it is either 0 or 1. Any combination of 0 and 1 is binary number such as 1001, 101, 11111, 101010 etc.
COSC 1336 – Programming Fundamentals IProgram 8 – Simple Functions Write in Python Program: The quadratic formula is used to solve a very specific type of equation, called a quadratic equation. These equations are usually written in the following form:ax2 + bx + c = 0The Quadratic Formula x = ( -b ± √( b^2 - 4ac ) ) / ( 2a ) Where a, b, and c are constants with a ≠ 0. (If a = 0, the equation is a linear equation.)The discriminant is the part of the formula in the square root. If the value of the discriminant is zero then the equation has a single real root. If the value of the discriminant is positive then the equation has two real roots. If the value of the discriminant is negative, then the equation has two complex roots.Write a program that finds the roots of the quadratic equation using the Quadratic Formula. Write a function named discriminant in the file, Disc.py, to calculate and return the discriminant of the formula. Let the main function call the discriminant function and…
JAVA LANGUAGE Body Mass Index Version 2.0 by CodeChum Admin Recall that according to the National Heart, Lung, and Blood Institute of the National Institutes of Health, body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It is used to monitor one's health by determining whether one is underweight, overweight, has normal weight or is obese. It is computed based as follows (when using standard weight in pounds and height in inches): BMI = 703 x (weight/(height2)) Furthermore, people with BMI scores that are less than 18.5 are said to be underweight. Those with scores between 18.5–24.9 (inclusive) are of normal weight. Those with scores between 25–29.9 (inclusive) are said to be overweight. And those with scores 30 or higher are obese. Input The input is composed of two positive integers representing the weight in pounds and the height in inches. 140·65 Output A single line containing two values: the computed…
CSCI 2436:01L Data Structures Lab Lab 1 - Chapter 4 The Efficiency of Algorithms In this lab, you will practice how to measure the running time f a section of code in Java. One approach is to use System.nano Time() where the current time is stored as a long integer equals to the number of nanoseconds. By subtracting the starting time in nanoseconds from the ending time in nanoseconds, you get the run time-in nanoseconds of a section of code. public static void main(String[] args) { int n1 = 10, n2 = 100, n3 = 1000, n4 = 10000; long n1Time, n2Time, n3Time, n4Time; n1Time AlgorithmA (nl); For example, suppose that AlgorithmA is the name of a method you wish to time. The following statements will compute the number of nanoseconds that AlgorithmA requires to execute: } public static long AlgorithmA (int n) { long startTime, endTime, elapsedTime; startTime = System.nanoTime (); int sum = 0; for (int i = 1; i 0 1 2.
