Uses two main attributes of each node to track reachability, the index of that node within a component(index),

We then perform a dfs of the each component making sure to update these parameters for each node and saving the

If ever we find that the lowest reachable node from a current node is equal to the index of the current node then it

Highly divisible triangular numbers
|
||||
Problem 12
|
||||
The sequence of triangle numbers is generated by adding the natural numbers. So the 7th triangle number would be 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28. The first ten terms would be:
|
||||
|
||||
1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ...
|
||||
|
||||
Let us list the factors of the first seven triangle numbers:
|
||||
|
||||
1: 1
|
||||
3: 1,3
|
||||
6: 1,2,3,6
|
||||
10: 1,2,5,10
|
||||
15: 1,3,5,15
|
||||
21: 1,3,7,21
|
||||
28: 1,2,4,7,14,28
|
||||
We can see that 28 is the first triangle number to have over five divisors.
|
||||
|
||||
What is the value of the first triangle number to have over five hundred divisors?

Amicable Numbers
|

Problem 21
|
||||
|
||||
Let d(n) be defined as the sum of proper divisors of n (numbers less than n which divide evenly into n).
|
||||
If d(a) = b and d(b) = a, where a ≠ b, then a and b are an amicable pair and each of a and b are called amicable numbers.
|
||||
|
||||
For example, the proper divisors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55 and 110; therefore d(220) = 284. The proper divisors of 284 are 1, 2, 4, 71 and 142; so d(284) = 220.

into alphabetical order. Then working out the alphabetical value for each name, multiply this value by its alphabetical position in the list
|
||||
to obtain a name score.
|
||||
|
||||
For example, when the list is sorted into alphabetical order, COLIN, which is worth 3 + 15 + 12 + 9 + 14 = 53, is the 938th name in the list.
|
||||
So, COLIN would obtain a score of 938 × 53 = 49714.
|

|
||||
What is the total of all the name scores in the file?

# ProjectEuler
|

|
||||
Problems are taken from https://projecteuler.net/.
|
||||
|
||||
Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical
|
||||
insights to solve. Project Euler is ideal for mathematicians who are learning to code.
|
||||
|
||||
Here the efficiency of your code is also checked.
|
||||
I've tried to provide all the best possible solutions.
|
||||
|
||||
PROBLEMS:
|
||||
|
||||
1. 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 N.
|
||||
|
||||
2. 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 n, find the sum of the even-valued terms.
|
||||
e.g. for n=10, we have {2,8}, sum is 10.
|
||||
|
||||
3. The prime factors of 13195 are 5,7,13 and 29. What is the largest prime factor of a given number N?
|
||||
e.g. for 10, largest prime factor = 5. For 17, largest prime factor = 17.
|
||||
|
||||
4. 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 which is less than N.
|
||||
|
||||
5. 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(divisible with no remainder) by all of the numbers from 1 to N?
|
||||
|
||||
6. The sum of the squares of the first ten natural numbers is,
|
||||
1^2 + 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.
|
||||
Find the difference between the sum of the squares of the first N natural numbers and the square of the sum.
|
||||
|
||||
7. 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 Nth prime number?
|
||||
|
||||
9. A Pythagorean triplet is a set of three natural numbers, a < b < c, for which,
|
||||
a^2 + b^2 = c^2
|
||||
There exists exactly one Pythagorean triplet for which a + b + c = 1000.
|
||||
Find the product abc.
|
||||
|
||||
14. The following iterative sequence is defined for the set of positive integers:
|
||||
n → n/2 (n is even)
|
||||
n → 3n + 1 (n is odd)
|
||||
Using the rule above and starting with 13, we generate the following sequence:
|
||||
13 → 40 → 20 → 10 → 5 → 16 → 8 → 4 → 2 → 1
|
||||
Which starting number, under one million, produces the longest chain?
|
||||
|
||||
16. 2^15 = 32768 and the sum of its digits is 3 + 2 + 7 + 6 + 8 = 26.
|
||||
What is the sum of the digits of the number 2^1000?
|
||||
20. n! means n × (n − 1) × ... × 3 × 2 × 1
|
||||
For example, 10! = 10 × 9 × ... × 3 × 2 × 1 = 3628800,
|
||||
and the sum of the digits in the number 10! is 3 + 6 + 2 + 8 + 8 + 0 + 0 = 27.
|
||||
Find the sum of the digits in the number 100!
