Project Euler is a series of math problems designed to be solved through programming solutions. I’ll be attempting to tackle these problems using PL/SQL and posting my solutions when I solve an answer.
Multiples of 3 and 5
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 1000.
DECLARE upper_limit INTEGER := 999; answer INTEGER := 0; BEGIN FOR i IN 1..upper_limit LOOP --check if i is divisible by 3 or 5 IF REMAINDER(i,3) = 0 OR REMAINDER(i,5) = 0 THEN answer := answer + i; END IF; END LOOP; dbms_output.put_line(answer); END; -- output: 233168
A pretty straight forward problem and solution here. I suppose you could create a function for checking the divisibility of each number, but I don’t think the extra code would any any more clarity in this case.
