get smallest positive number form array.
if no positive number in array, return 0.
example:
var list1 = [0, 1, 1, 3];
var list2 = [7, 2, null, 3, 0, 10];
var list2 = [null];
getMin(list1); //should return 1
getMin(list2); //should return 2
getMin(list3); //should return 0
var getMin = function (list){
var min = Number.MAX_VALUE;
for (var i = 0; i < list.length; i++) {
if (+list[i] <= 0) {
continue;
}
min = Math.min(min, +list[i]);
}
return min = min === Number.MAX_VALUE ? 0 : min;
