Which is the correct solution for Project Euler?
The correct solution to the original Project Euler problem was found in less than 0.01 seconds on an Intel® Core™ i7-2600K CPU @ 3.40GHz. See here for a comparison of all solutions.
How many empty lines are in Project Euler?
This solution contains 7 empty lines, 4 comments and 1 preprocessor command. The correct solution to the original Project Euler problem was found in less than 0.01 seconds on an Intel® Core™ i7-2600K CPU @ 3.40GHz. See here for a comparison of all solutions.
Which is harder Project Euler or HackerRank?
5% Project Euler ranks this problem at 5% (out of 100%). Hackerrank describes this problem as easy . Hackerrank has strict execution time limits (typically 2 seconds for C++ code) and often a much wider input range than the original problem. In my opinion, Hackerrank’s modified problems are usually a lot harder to solve.
How to calculate multiples of 3 and 5?
3 imes \\sum {x/3} 3×∑x/3. However, there are numbers divisible by 3 and 5, which means they are part of both sums. compute the sum of all numbers divisible by 3*5=15 to correct for this error. whether they are divisible by 3 or 5 easily solves the problem, too, and produces the result pretty much instantly.

Which is the largest product in a grid?
In the 20×20 grid below, four numbers along a diagonal line have been marked in red. The product of these numbers is 26 x 63 x 78 x 14 = 1788696. (up, down, left, right, or diagonally) in the 20×20 grid?
Project Euler Problem 11: Largest Product In A Grid¶ The source code for this problem can be found here. Problem Statement¶ In the \\(20 imes 20\\)grid below, four numbers along a diagonal line have been marked in red.
What is the greatest product of four adjacent numbers in the same direction?
In the 20×20 grid below, four numbers along a diagonal line have been marked in red. The product of these numbers is 26 × 63 × 78 × 14 = 1788696. What is the greatest product of four adjacent numbers in the same direction (up, down, left, right, or diagonally) in the 20×20 grid?
The correct solution to the original Project Euler problem was found in 0.22 seconds on an Intel® Core™ i7-2600K CPU @ 3.40GHz. Peak memory usage was about 30 MByte. See here for a comparison of all solutions.
Is it worth the time to run Euler solutions?
The style of using generators/ filters/ itertools can be considered about halfway between Java’s imperative style and {Haskell or Mathematica}’s functional style. Unfortunately due to Python’s slow performance on arrays and machine-word-sized integer values, many solutions are not worth the time to run it compared to the Java implementations.
Which is the best library for solving Haskell problems?
Many Haskell solutions depend on my shared math library module: EulerLib.hs. Some solution code contains a detailed mathematical proof of correctness. For every problem that I solved, I have a Java solution for it (and possibly code in other languages as well). I like using Java because it is fast, safe, and expressive.
The correct solution to the original Project Euler problem was found in 1.5 seconds on an Intel® Core™ i7-2600K CPU @ 3.40GHz. See here for a comparison of all solutions.
20% Project Euler ranks this problem at 20% (out of 100%). Hackerrank describes this problem as easy .

In my opinion, Hackerrank’s modified problems are usually a lot harder to solve.
What kind of program do I use to solve my problems?
Almost all my solved problems also include a Python program (except for a few). Many problems additionally have a Mathematica and Haskell program. Numerous solutions contain a detailed mathematical proof to justify why the implemented algorithm is correct.
