It can be seen that for a hexagonal orchard of order $5$, $30$ points are hidden from the center. Medium Max Score: 100 Success Rate: 67. I've made it mostly work, but it still outputs 173, instead of 171 (the correct answer). For example, if the passcode was 531278, they may ask for the 2nd, 3rd, and 5th characters; the expected reply would be: 317. 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 //Project Euler #171: Finding numbers for which the sum of the squares of the digits is a square #include <iostream> #include <math. The first thing I checked was the gcd(1504170715041707, 4503599627370517) and it is indeed equal to 1, this means that there is a Multiplicative inverse, that is there is a number x such that 1504170715041707 *x = 1 mod(4503599627370517), this x is equal to 3451657199285664. the key is you should save previous results in a dictionary so you don't have to compute those results again.

The people that posed the questions at Math Overflow, in my opinion have shown to lack the mental attitude to do the necessary doodling around. We can also use the formula that the sum of the first n integers is n n+1 2. - nayuki/Project-Euler-solutions A website dedicated to the fascinating world of mathematics and programming A common security method used for online banking is to ask the user for three random characters from a passcode. Peak memory usage was about 22 MByte. Problem 321 Project Euler > Problem 69 > Totient maximum (Java Solution) Problem: Euler's Totient function, φ(n) [sometimes called the phi function], is used to determine the number of numbers less than n which are relatively prime to n.
