This page lists all of my Project Euler solution code, along with other helpful information like benchmark timings and my overall thoughts on the nature of math and programming in Project Euler. They'll want you to manipulate numbers like strings, like arrays of digits, and as normal numbers. I've successfully tackled this question for the given examples, my function can correctly find f(9), f(10), etc. This article is a full walkthrough on Project Euler problem 4. Prime Factor Rather than try and explain it in my own words, i'll let mathisfun.com do the explaining. (Java Solution), Project Euler > Problem 175 > Fractions involving the number of different ways a number can be expressed as a sum of powers of 2. So the determined participant will slowly but surely work his/her way through every problem. The solutions are hosted on GitHub. Atom (Java Solution) Project Euler > Problem 177 > Integer angled Quadrilaterals. I know I can write it using binomials but I wanted to calculate by brute force as if I do not know Binomials. This can be rough in languages that don't really support this. Here's an example: If we take 47, reverse and add, 47 + 74 = 121, which is palindromic. Worked example: Euler's method. (Java Solution), Project Euler > Problem 178 > Step Numbers (Java Solution), Project Euler > Problem 179 > Consecutive positive divisors (Java Solution), Project Euler > Problem 180 > Rational zeros of a function of three variables. Solution. Problem 32 of Project Euler is about a special kind of number ... for example, the 5-digit number, 15234, is 1 through 5 pandigital. (Java Solution), Project Euler > Problem 174 > Counting the number of "hollow" square laminae that can form one, two, three, ... distinct arrangements. Project Euler > Problem 175 > Fractions involving the number of different ways a number can be expressed as a sum of powers of 2. Submissions. (Java Solution), Project Euler > Problem 171 > Finding numbers for which the sum of the squares of the digits is a square. The sum of these multiples is 23. I still need a break. A series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve.
