Nostalgia
A little more than two years ago, I started experiencing a very unique feeling, the sort of complex emotion that’s hard to put into words, but that I’d describe as a “bittersweet, existential, anxiety-inducing nostalgia.” I’m not quite sure how else to put it, and I’m writing this as a way to see if putting it into words can help me clarify it in a more…

10001st prime
By listing the first six prime numbers: 2, 3, 5, 7, 11, and 13, we can see that the 6th prime is 13. What is the 10 001st prime number? At first glance, a simple iteration whilst checking if index position is prime, would suffice. A pseudocode attempt: sum = 0 for i = 2; i <= ?; i++ { if(isPrime(i)){ sum++ if ( sum >= 10001) { return i } } } Using the solution in go to check if is prime from…
Sum square difference
The sum of the squares of the first ten natural numbers is, $$ 1^x1D2 + 2^2 + … + 10^2 = 385 $$ The square of the sum of the first ten natural numbers is, $$ (1 + 2 + … + 10)^2 = 552 = 3025 $$ Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is 3025 − 385 = 2640.
Smallest multiple
2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder. What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20? At first glance, and as a concept refresher, we’ll have to use **GCD* and **LCM**. GCD stands for Greatest Common Divisor . GCD is the largest number that divides the given numbers. LCM…
Largest palindrome product
A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 × 99. Find the largest palindrome made from the product of two 3-digit numbers The first observation is that the number should be in the range of 10000 and 998001 . There’s a couple aproaches to the problem, such as: Multiplicating two 3-digit numbers and checking…
Largest prime factor
The prime factors of 13195 are 5, 7, 13 and 29. What is the largest prime factor of the number 600851475143 ? We neeed to find the largest prime factor of 600851475143 . We know that the largest prime factor of a number, its the number itself. As a concept refresher, any prime number is only divisible by 1 ant itself, thus, when dividing by a certain number, there should not be a reminder.
Even Fibonacci numbers
Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, … By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms. package main import ( 'fmt' 'time' ) func main () { start := time . Now () i , c ,…
Multiples of 3 and 5
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000. package main import 'fmt' func main () { sum := 0 for i := 0 ; i < 1000 ; i ++ { if i % 3 == 0 || i % 5 == 0 { sum += i } } fmt . Print ( sum ) } Answer: 233168
