Dovy's problem

An array has a special property which is the following:
Every number which is ahead of another is bigger than the sum of the previous ones.
Could you write a function to verify if this specific array exhibits this property?

Example array:
1, 2, 4, 8, 30

Solution, pseudocode:
function verify(array):
	sum = 0
	for(i = 0; i < array.length; i++):
		if sum > array[i]:
			return false
		sum += array[i]
	return true

Solution, python:
def verify(array):
	sum = 0
	for i in array:
		if sum > i:
			return false
		sum += i
	return true
