Problem_1.markdown

The following is the description of first problem we need to solve, try finish it before Friday. There's no rule to complete the issue, you can use either languages with either way. Clean code is also not a requirement. In another way, there's no "Jiecao" to finish that.

Problem 1

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.

Problem from

(1...1000).inject(0) {|sum, value| (value.modulo(3).zero? or value.modulo(5).zero?) ? sum + value : sum}

_.reduce(_.range(1000), function(memo, num){ if (num % 3 === 0 || num % 5 === 0){ return memo+num; }else{ return memo;} }, 0);
