Project Euler/1

← Back to User:ProjectEuler

The first problem from Project Euler is a problem very similar to FizzBuzz. The major differences are:

• FizzBuzz usually counts to 100, while Project Euler counts to 999 (Not one thousand!).
• FizzBuzz prints the numbers and replaces the multiples of 3 and 5 with certain words, while Project Euler adds the multiples of 3 and 5 up, and prints that sum.

This program needs reduction due to no-op chains.

This program unfortunately fails on Try It Online, probably because Try It Online does not allow setting the value to 0.

C

#include <stdio.h>
i=0,r=0;main(){while(i++<999)if(i%3==0||i%5==0)r+=i;printf("%d",r);}

Python

By User:None1:

print(sum(filter(lambda x:x%3==0 or x%5==0,range(1,1000))))

This code may be shortened using the operators "cube" and "remainder".

The Euler Plan.
Hamlet, who adds everything up.
Juliet, who always counts down.

Act I:a.
Scene I: define constant.
[ enter Hamlet and Juliet ]
Hamlet: You are twice twice twice the sum of the sum of a big big big big big big big cat and a big pig and a pig.

Scene II: start loop.

Hamlet: you are the sum of you and a pig.
Hamlet: Are you as good as the product of the quotient between you and the sum of a big cat and a cat and the sum of a big cat and a cat?

If so, let us proceed to Scene III.
Hamlet: Are you as good as the product of the quotient between you and the sum of a big big cat and a cat and the sum of a big big cat and a cat?

If so, let us proceed to Scene III.
If not, let us proceed to Scene II.
Scene III: Add numbers.
Juliet: You are the sum of you and me.
Hamlet: Are you as good as nothing? If not, let us proceed to Scene II.
Juliet: Open your heart.

有數零。名之曰「H」。
有數千。名之曰「J」。
恆為是。若「J」等於零者乃止也。
  減「J」以一。昔之「J」者。今其是矣。
	除「J」以三。所餘幾何。
	若其等於零者。
	  加「H」以「J」。昔之「H」者。今其是矣。
	若非。
	  除「J」以五。所餘幾何。
	 若其等於零者。
	   加「H」以「J」。昔之「H」者。今其是矣。
