In class we explained that the one time pad is malleable. let’s see a concrete example. suppose you are told that the one time pad encryption of the message ""attack at dawn"" is 09e1c5f70a65ac51626bc3d25f17 (the plaintext letters are encoded as 8-bit ascii and the given ciphertext is written in hex). what would be the one time pad encryption of the message ""attack at dusk"" under the same otp key?

Write a program that prints the day number of the year, given the date in the form month-day-year. for example, if the input is 1-1-2006, the day number is 1; if the input is 12-25-2006, the day number is 359. the program should check for a leap year. a year is a leap year if it is divisible by 4, but not divisible by 100. for example, 1992 and 2008 are divisible by 4, but not by 100. a year that is divisible by 100 is a leap year if it is also divisible by 400. for example, 1600 and 2000 are divisible by 400. however, 1800 is not a leap year because 1800 is not divisible by 400.
