ClockHands  The medieval interest in mechanical contrivances is well illustrated by the development of the mechanical clock, the oldest of which is driven by weights and controlled by a verge

Pseudo-Random Numbers Computers normally cannot generate really random numbers, but frequently are used to generate sequences of pseudo-random numbers. These are generated by some algor

Uniform Generator Computer simulations often require random numbers. One way to generate pseudo-random numbers is via a function of the form where `` " is the modulus operator

Just the Facts  The expression N!, read as ``N factorial," denotes the product of the firstN positive integers, where N is nonnegative. So, for example, N N! 0 1 1

Multiplying by Rotation  Warning: Not all numbers in this problem are decimal numbers! Multiplication of natural numbers in general is a cumbersome operation. In some cases however

Light, more light The Problem There is man named "mabu" for switching on-off light in our University. He switches on-off the lights in a corridor. Every bulb has its own toggle switch. That

Skew Binary  When a number is expressed in decimal, the k-th digit represents a multiple of 10k. (Digits are numbered from right to left, where the least significant digit is number 0.) For example,

The Cat in the Hat  Background (An homage to Theodore Seuss Geisel) The Cat in the Hat is a nasty creature, But the striped hat he is wearing has a rather nifty feature. With one

Problem G How many zeros and how many digits? Input: standard input Output: standard output   Given a decimal integer number you will have to find out how many trailing zeros will be there in i

Problem B Code Refactoring Time Limit: 2 seconds "Harry, my dream is a code waiting to be broken. Break the code, solve the crime." Agent Cooper Several algorithms in mode

Problem F: Factoring Large Numbers One of the central ideas behind much cryptography is that factoring large numbers is computationally intensive. In this context one might use a 100 digit number t
