Alice signs the hash of a message. Suppose her hash function satisfies h(x) = 2ª (mod 101) and 1< h(x) < 100 for all x. Suppose m is a valid signed message from Alice. Give another message m1 for which the same signature is also valid.

Here's some background information on our Gregorian calendar. Although the Gregoriancalendar was created in 1582, The United States did not adopt it until 1752. Therefore, theGregorian calendar formula for calculating leap years only applies to years 1752 and later in theUnited States. The Gregorian calendar provided an improved formula for calculating whichyears are Leap Years. The criteria for a determining whether a year is a Leap Year is:Leap Year Definition:• The year is evenly divisible by 4; • If the year can be evenly divided by 100, it is NOT a leap year, unless;• The year is also evenly divisible by 400. Then it is a leap year.Your assignment is to create a Python program that in general uses a function to determinewhether a year is a leap year and another function for obtaining year input values from the user.More specifically your program should:1. Contain a function that determines whether a year passed to it is:a. A valid year for the Gregorian calendar usage in the…

The Problem A Zeckendorf number is defined for all positive integers as the number of Fibonacci numbers which must be added to equal a given number k. So, the positive integer 28 is the sum of three Fibonacci numbers (21, 5, and 2), so the Zeckendorf number for k = 28 is three. Wikipedia is a satisfactory reference for our purposes for more details of the Zeckendorf and Fibonacci numbers. In both cases, you do not need to read the entire Wikipedia entry. Your assignment is to write two ARM assembly language functions which calculate Zeckendorf and Fibonacci numbers. Zeck function The first function, which should be named zeck, receives an integer parameter in register zero. This will be the variable k we discussed above. Your code should return the Zeckendorf number for k in register zero when complete. If the parameter k is zero, return zero. If the parameter k is negative, return minus 1. If the parameter k is too large to calculate, return minus 1. Fib function The other function,…

File sizes are measured in bytes (8 bits). A 24 megapixel camera's recording chip might have a 4000 X 6000 grid of pixels-- that's 24 million pixels. if each uses 8 bits for each color, (red gren blue), each image will produce a 72 megabytes file. Q:

Part 3: Factorial function In computer science, and other fields, we frequently need to know how many possible combinations are possible given a specific number of numbers or characters. For example, consider three color cards: red (R), green (G), and blue (B). How many different orders are possible of these three cards? RGB, RBG, GRB, GBR, BRG, BGR = six (6) possible combinations The mathematical term for this calculation is factorial (see Factorial Function !Links to an external site. web page) and is expressed using the exclamation point (!). Surprisingly, the JavaScript Math object does not have a function for factorial, so we will write our own. So how do we calculate factorial? The steps to accomplish a task are known as an algorithm. An algorithm is a series of steps that given the same input will always produce the same output. Often, many possible algorithms exist to accomplish the same task. To calculate the factorial of a specific number, we need to multiply every number…
