var summarize = function(array) {
	var i = 0
	var sum = 0
	var newArray = array()   
	while(i < length(array)) {
		if(verifyArrayAsValid(get(array,i))) {
			sum = sumUpArray(get(array,i))
			newArray = insert(newArray, length(newArray), sum)
		}
		i = i + 1
	}
	return newArray
}

var verifyArrayAsValid = function(array) {
	var i = 0
	var status = true
	while(i < length(array)) {
		if(get(array,i) <= 0) {
			status = false
		}
		i = i + 1
	}
	return status
}

var sumUpArray = function(array) {
	var i = 0
	var sum = 0
	while(i < length(array)) {
		sum = sum + get(array,i)
		i = i + 1
	}
	return sum
