Question 1: "Pseudorandom Numbers"
Develop a recursive linear congruential number generating function that is a given an
element of the sequence Xi as an argument and will produce the floating-point value between
0 and 1 (inclusive) that is to be the next element of the sequence. You will need to...
Input:
A decimal
Output:
The input truncated
How to truncate them?
The integer part of the input will remain the same. The decimal part of the input will be truncated based on the lowest digit in consecutive order. The two step-by-step examples below should clarify what I mean by that:

Dirichlet Convolution

The Dirichlet convolution is a special kind of convolution that appears as a very useful tool in number theory. It operates on the set of arithmetic functions, and there is even a identit...
There is a "sorting algorithm" sometimes called Stalin sort in which in order to sort a list you simply remove elements from the list until it is sorted. For example the list
[1, 2, 4, 5, 3, 6, 6]
When "sorted" using Stalin sort becomes
[1, 2, 4, 5, 6, 6]
The three was removed because it w...
Someone sent me this description of a joke sorting algorithm, and I thought it would make for a fun golf.
Given a list of positive integers remove all elements that aren't larger than all elements that precede them. Here's an example in Haskell.
stalin :: [Int] -> Int -> [Int]
stalin [] n = []

Generate a random number (in the millions) like 2,000,000. Then increase the number a million each time in 8 times. Your code should display like this:
random number
randomnum+1000,0000
randomnum+2000,0000
until you increase it a million each time eight times.
Introduction
Your challenge today is to output the lyrics of "99 bottles of beer":
99 bottles of beer on the wall, 99 bottles of beer.
Take one down and pass it around, 98 bottles of beer on the wall.
98 bottles of beer on the wall, 98 bottles of beer.
Take one down and pass it around, 97 bott...
Is this a Major Scale
The major scale (or Ionian scale) is one of the most commonly used musical scales, especially in Western music. It is one of the diatonic scales. Like many musical scales, it is made up of seven notes: the eighth duplicates the first at double its frequency so that it is ca...
Here are the basics.
There are 200 people on a train, all with assigned seats.
The first person to board does not sit in his seat, and takes a random seat.
If a person discovers their seat has been taken, they will take a random seat.
If their seat isn’t taken, they will ...
