Last active December 22, 2015 06:58
Solution for Reaktor's programming task at http://reaktor.fi/ura/fast_track/ This solution relies on the fact that JavaScript can solve multiplication for strings (e.g. "2" * "3" -> 6) and thus parseInt is not needed.
function (input) {
function product(numbers) {
if (numbers.indexOf("0") !== -1) {
return 0
} else {
return _(numbers).reduce(function(product, number){
return product * number
}, 1)
}
}
