is 5‚ the output will be 1 3 6 10 15 5 Write a program to implement the Russian Peasant Problem for multiplying two positive numbers using while or do…while loop. Russian Peasant problem is a method of multiplying two numbers together‚ using only division by 2‚ multiplication by 2 and addition. For example‚ if the numbers are 17 and 19are to be multiplied together‚ they are put at the head of two columns: The first number is divided by 2 and the second number is multiplied by 2.

Linear Application and Hill Cipher. Cryptography has played an important role in information and communication security for thousand years. It was first invented due to the need to maintain the secrecy of information transmitted over public lines. The word cryptography came from the Greek words kryptos and graphein‚ which respectively mean hidden and writing (Damico). Since the ancient days‚ many forms of cryptography have been created. And in 1929‚ Lester S. Hill‚ an American mathematician and

priori (before hand). In this case‚ we could use a while loop to determine that answer: The "pseudocode" for such an algorithm is: while the number is bigger than one keep dividing it by two. Additionally keep a count of how many times we do the division. Why While Loops: Like all loops‚ "while loops" execute blocks of code over and over again. The advantage to a while loop is that it will go (repeat) as often as necessary to accomplish its goal. while ( condition is true )

Q#1: For each pair of numbers‚ when the division algorithm is used to divide a by d‚ what are the quotient q and remainder r? (a) a = 88‚ d = 11. (b) a = −29‚ d = 9 (c) a = 58237‚ d = 58168 (actual question is a = 58237‚ d = 58168 ) Solution: (a) Because 88 = 11・8 + 0‚ we have q = 8‚ r = 0. (The fact that r = 0 says that 11|88.) (b) Because −29 = 9・(−4) + 7‚ we have q = −4 and r = 7. (Note that although we can write −29 =9・(−3) + (−2)‚ we cannot use −2 as r because r is
