Card Sharks Odds   (details) Prime   EN   3KB/2KB
The game show Card Sharks may have long been off-air except for reruns on GSN or BUZZR (or even finding videos on YouTube), the game show is still popular. It is a simple game involving a standard deck of 52 cards. The object is to predict whether the next card is higher in rank or lower in rank than the preceding card. In Card Sharks, aces always count as high. Along with aces, twos are very desirable, while eights are the worst cards in the deck. The program CSODDS tracks the odds of whether the next card is higher or lower. CSODDS assumes a 52 card deck (no jokers).

Carmichael Numbers   (details) Prime   EN   3KB/1KB
Tests whether an integer n qualifies as a Carmichael number based on the Korselt’s Criterion: 1. n is a positive, composite integer. That is, n can be factored into a multiplication of prime numbers. 2. n is square-free. 3. For each prime factor p dividing n (not 1 or n), the following is true: (p-1) divides (n-1) evenly (without fraction).
